-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-	- No longer weight providers on the basis of a package being "already staged". This
-	  leads to builds being non-deterministic.
-	- Flush stdout/stderr before forking to fix duplicate console output
-	- Make sure recrdeps tasks include all inter-task dependencies of a given fn

-	- Add PERSISTENT_DIR to store the PersistData in a persistent
-	  directory != the cache dir.
-	- Add md5 and sha256 checksum generation functions to utils.py
-	- Correctly handle '-' characters in class names (#2958)
-	- Make sure expandKeys has been called on the data dictionary before running tasks
-	- Correctly add a task override in the form task-TASKNAME.
-	- Revert the '-' character fix in class names since it breaks things
-	- When a regexp fails to compile for PACKAGES_DYNAMIC, print a more useful error (#4444)
-	- Allow to checkout CVS by Date and Time. Just add HHmm to the SRCDATE.
-	- Move prunedir function to utils.py and add explode_dep_versions function
-	- Raise an exception if SRCREV == 'INVALID'
-	- Fix hg fetcher username/password handling and fix crash
-	- Fix PACKAGES_DYNAMIC handling of packages with '++' in the name
-	- Rename __depends to __base_depends after configuration parsing so we don't
-	  recheck the validity of the config files time after time
-	- Add better environmental variable handling. By default it will now only pass certain 
-	  whitelisted variables into the data store. If BB_PRESERVE_ENV is set bitbake will use
-	  all variable from the environment. If BB_ENV_WHITELIST is set, that whitelist will be
-	  used instead of the internal bitbake one. Alternatively, BB_ENV_EXTRAWHITE can be used
-	  to extend the internal whitelist.
-	- Perforce fetcher fix to use commandline options instead of being overriden by the environment
-	- bb.utils.prunedir can cope with symlinks to directoriees without exceptions
-	- use @rev when doing a svn checkout
-	- Add osc fetcher (from Joshua Lock in Poky)
-	- When SRCREV autorevisioning for a recipe is in use, don't cache the recipe
-	- Add tryaltconfigs option to control whether bitbake trys using alternative providers
-	  to fulfil failed dependencies. It defaults to off, changing the default since this
-	  behaviour confuses many users and isn't often useful.
-	- Improve lock file function error handling

-Changes in Bitbake 1.8.0:
-	- Release 1.7.x as a stable series
-
-Changes in BitBake 1.7.x:
-	- Major updates of the dependency handling and execution

-	  into it
-	- git speedup cloning by not doing a checkout
-	- allow to have spaces in filenames (.conf, .bb, .bbclass)
-
-Changes in BitBake 1.4.0:
-	- Fix to check both RDEPENDS and RDEPENDS_${PN}
-	- Fix a RDEPENDS parsing bug in utils:explode_deps()

-	  (CVSDATE).
-	  Issue #555 fixed by chris@openedhand.com
-	- Expand PREFERRED_PROVIDER properly
-	  Issue #436 fixed by rprudie@openedhand.com
-	- Typo fix for Issue #531 by Philipp Zabel for the
-	  BitBake Shell
-	- Introduce a new special variable SRCDATE as
-	  a generic naming to replace CVSDATE.
-	- Introduce a new keyword 'required'. In contrast
-	  to 'include' parsing will fail if a to be included
-	  file can not be found.
-	- Remove hardcoding of the STAMP directory. Patch
-	  courtsey pHilipp Zabel
-	- Track the RDEPENDS of each package (rpurdie@openedhand.com)

-	  downloaded file was not found in DL_DIR (this is needed
-	  to avoid unpacking the sourceforge mirror page)
-	- Switch to a cow like data instance for persistent and non
-	  persisting mode (called data_smart.py)
-	- Changed the callback of bb.make.collect_bbfiles to carry
-	  additional parameters
-	- Drastically reduced the amount of needed RAM by not holding
-	  each data instance in memory when using a cache/persistent
-	  storage
-
-Changes in BitBake 1.2.1:
-	The 1.2.1 release is meant as a intermediate release to lay the
-	ground for more radical changes. The most notable changes are:
-
-	- Do not hardcode {}, use bb.data.init() instead if you want to
-	  get a instance of a data class
-	- bb.data.init() is a factory and the old bb.data methods are delegates
-	- Do not use deepcopy use bb.data.createCopy() instead.
-	- Removed default arguments in bb.fetch

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-.SH NAME
-BitBake \- simple tool for the execution of tasks
-.SH SYNOPSIS
-.B bitbake
-.RI [ options ] " packagenames"
-.br
-.SH DESCRIPTION
-This manual page documents briefly the
-.B bitbake
-command.
-.PP
-.\" TeX users may be more comfortable with the \fB<whatever>\fP and
-.\" \fI<whatever>\fP escape sequences to invode bold face and italics, 
-.\" respectively.
-\fBbitbake\fP is a program that executes the specified task (default is 'build')
-for a given set of BitBake files.
-.br
-It expects that BBFILES is defined, which is a space separated list of files to
-be executed. BBFILES does support wildcards.
-.br
-Default BBFILES are the .bb files in the current directory.
-.SH OPTIONS
-This program follow the usual GNU command line syntax, with long
-options starting with two dashes (`-').
-.TP
-.B \-h, \-\-help
-Show summary of options.
-.TP
-.B \-\-version
-Show version of program.
-.TP
-.B \-bBUILDFILE, \-\-buildfile=BUILDFILE
-execute the task against this .bb file, rather than a package from BBFILES.
-.TP
-.B \-k, \-\-continue
-continue as much as possible after an error. While the target that failed, and
-those that depend on it, cannot be remade, the other dependencies of these
-targets can be processed all the same.
-.TP
-.B \-a, \-\-tryaltconfigs
-continue with builds by trying to use alternative providers where possible.
-.TP
-.B \-f, \-\-force
-force run of specified cmd, regardless of stamp status
-.TP
-.B \-i, \-\-interactive
-drop into the interactive mode also called the BitBake shell.
-.TP
-.B \-cCMD, \-\-cmd=CMD
-Specify task to execute. Note that this only executes the specified task for
-the providee and the packages it depends on, i.e. 'compile' does not implicitly
-call stage for the dependencies (IOW: use only if you know what you are doing).
-Depending on the base.bbclass a listtasks task is defined and will show
-available tasks.
-.TP
-.B \-rFILE, \-\-read=FILE 
-read the specified file before bitbake.conf
-.TP
-.B \-v, \-\-verbose
-output more chit-chat to the terminal
-.TP
-.B \-D, \-\-debug
-Increase the debug level. You can specify this more than once.
-.TP
-.B \-n, \-\-dry-run
-don't execute, just go through the motions
-.TP
-.B \-p, \-\-parse-only
-quit after parsing the BB files (developers only)
-.TP
-.B \-d, \-\-disable-psyco
-disable using the psyco just-in-time compiler (not recommended)
-.TP
-.B \-s, \-\-show-versions
-show current and preferred versions of all packages
-.TP
-.B \-e, \-\-environment
-show the global or per-package environment (this is what used to be bbread)
-.TP
-.B \-g, \-\-graphviz
-emit the dependency trees of the specified packages in the dot syntax
-.TP
-.B \-IIGNORED\_DOT\_DEPS, \-\-ignore-deps=IGNORED_DOT_DEPS
-Stop processing at the given list of dependencies when generating dependency
-graphs. This can help to make the graph more appealing
-.TP
-.B \-lDEBUG_DOMAINS, \-\-log-domains=DEBUG_DOMAINS
-Show debug logging for the specified logging domains
-.TP
-.B \-P, \-\-profile
-profile the command and print a report
-.TP

-        <section>
-            <title>Overview</title>
-            <para>BitBake is, at its simplest, a tool for executing
-tasks and managing metadata.  As such, its similarities to GNU make and other
-build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions, including OpenZaurus and Familiar.</para>
-        </section>
-        <section>
-            <title>Background and Goals</title>
-            <para>Prior to BitBake, no other build tool adequately met
-the needs of an aspiring embedded Linux distribution.  All of the
-buildsystems used by traditional desktop Linux distributions lacked
-important functionality, and none of the ad-hoc
-<emphasis>buildroot</emphasis> systems, prevalent in the
-embedded space, were scalable or maintainable.</para>
-
-      <para>Some important goals for BitBake were:
-            <itemizedlist>
-                <listitem><para>Handle crosscompilation.</para></listitem>
-                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
-                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
-                <listitem><para>Must be linux distribution agnostic (both build and target).</para></listitem>
-                <listitem><para>Must be architecture agnostic</para></listitem>
-                <listitem><para>Must support multiple build and target operating systems (including cygwin, the BSDs, etc).</para></listitem>
-                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
-                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
-                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
-                <listitem><para>Must make it easy to collaborate
-between multiple projects using BitBake for their
-builds.</para></listitem>
-		<listitem><para>Should provide an inheritance mechanism to
-share common metadata between many packages.</para></listitem>
-                <listitem><para>Et cetera...</para></listitem>
-            </itemizedlist>
-        </para>
-        <para>BitBake satisfies all these and many more.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

-        <title>Metadata</title>
-        <section>
-            <title>Description</title>
-            <itemizedlist>
-                <para>BitBake metadata can be classified into 3 major areas:</para>
-                <listitem>
-                    <para>Configuration Files</para>
-                </listitem>
-                <listitem>
-                    <para>.bb Files</para>
-                </listitem>
-                <listitem>
-                    <para>Classes</para>
-                </listitem>
-            </itemizedlist>
-            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
-            <section>
-                <title>Basic variable setting</title>
-                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>
-                <para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
-            </section>
-            <section>
-                <title>Variable expansion</title>
-                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>
-                <para><screen><varname>A</varname> = "aval"
-<varname>B</varname> = "pre${A}post"</screen></para>
-                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
-            </section>
-            <section>
-                <title>Setting a default value (?=)</title>
-                <para><screen><varname>A</varname> ?= "aval"</screen></para>
-                <para>If <varname>A</varname> is set before the above is called, it will retain it's previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
-            </section>
-            <section>
-                <title>Setting a default value (??=)</title>
-                <para><screen><varname>A</varname> ??= "somevalue"</screen></para>
-                <para><screen><varname>A</varname> ??= "someothervalue"</screen></para>
-                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy version of ??=, in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used.</para>
-            </section>
-            <section>
-                <title>Immediate variable expansion (:=)</title>
-                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>
-                <para><screen><varname>T</varname> = "123"
-<varname>A</varname> := "${B} ${A} test ${T}"
-<varname>T</varname> = "456"
-<varname>B</varname> = "${T} bval"
-
-<varname>C</varname> = "cval"
-<varname>C</varname> := "${C}append"</screen></para>
-                <para>In that example, <varname>A</varname> would contain <literal> test 123</literal>, <varname>B</varname> would contain <literal>456 bval</literal>, and <varname>C</varname> would be <literal>cvalappend</literal>.</para>
-            </section>
-            <section>
-                <title>Appending (+=) and prepending (=+)</title>
-                <para><screen><varname>B</varname> = "bval"
-<varname>B</varname> += "additionaldata"
-<varname>C</varname> = "cval"
-<varname>C</varname> =+ "test"</screen></para>
-                <para>In this example, <varname>B</varname> is now <literal>bval additionaldata</literal> and <varname>C</varname> is <literal>test cval</literal>.</para>
-            </section>
-            <section>
-                <title>Appending (.=) and prepending (=.) without spaces</title>
-                    <para><screen><varname>B</varname> = "bval"
-<varname>B</varname> .= "additionaldata"
-<varname>C</varname> = "cval"
-<varname>C</varname> =. "test"</screen></para>
-                <para>In this example, <varname>B</varname> is now <literal>bvaladditionaldata</literal> and <varname>C</varname> is <literal>testcval</literal>. In contrast to the above Appending and Prepending operators no additional space
-will be introduced.</para>
-            </section>
-            <section>
-                <title>Conditional metadata set</title>
-                <para>OVERRIDES is a <quote>:</quote> separated variable containing each item you want to satisfy conditions.  So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>
-                <para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
-<varname>TEST</varname> = "defaultvalue"
-<varname>TEST_os</varname> = "osspecificvalue"
-<varname>TEST_condnotinoverrides</varname> = "othercondvalue"</screen></para>
-                <para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>
-            </section>
-            <section>
-                <title>Conditional appending</title>
-                <para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES.  Example:</para>
-                <para><screen><varname>DEPENDS</varname> = "glibc ncurses"
-<varname>OVERRIDES</varname> = "machine:local"
-<varname>DEPENDS_append_machine</varname> = " libmad"</screen></para>
-                <para>In this example, <varname>DEPENDS</varname> is set to <literal>glibc ncurses libmad</literal>.</para>
-            </section>
-            <section>
-                <title>Inclusion</title>
-                <para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse in whatever file you specify, and insert it at that location, which is not unlike <command>make</command>.  However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>
-            </section>
-            <section>
-                <title>Requiring Inclusion</title>
-                <para>In contrast to the <literal>include</literal> directive, <literal>require</literal> will
-raise an ParseError if the to be included file can not be found. Otherwise it will behave just like the <literal>
-include</literal> directive.</para>

-                <para>The <literal>inherit</literal> directive is a means of specifying what classes of functionality your .bb requires.  It is a rudimentary form of inheritance.  For example, you can easily abstract out the tasks involved in building a package that uses autoconf and automake, and put that into a bbclass for your packages to make use of.  A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>

-                <para>In BitBake, each step that needs to be run for a given .bb is known as a task.  There is a command <literal>addtask</literal> to add new tasks (must be a defined python executable metadata and must start with <quote>do_</quote>) and describe intertask dependencies.</para>
-                <para><screen>python do_printdate () {
-    import time

-}
-
-addtask printdate before do_build</screen></para>
-                <para>This defines the necessary python function and adds it as a task which is now a dependency of do_build (the default task).  If anyone executes the do_build task, that will result in do_printdate being run first.</para>

-                <para>BitBake allows to install event handlers.  Events are triggered at certain points during operation, such as, the beginning of operation against a given .bb, the start of a given task, task failure, task success, et cetera.  The intent was to make it easy to do things like email notifications on build failure.</para>
-                <para><screen>addhandler myclass_eventhandler

-                <title>Variants</title>
-                <para>Two Bitbake features exist to facilitate the creation of multiple buildable incarnations from a single recipe file.</para>
-                <para>The first is <varname>BBCLASSEXTEND</varname>.  This variable is a space separated list of classes to utilize to "extend" the recipe for each variant.  As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarantion will have the "native" class inherited.</para>
-                <para>The second feature is <varname>BBVERSIONS</varname>.  This variable allows a single recipe to be able to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>

-usage: bitbake [options] [package ...]
-
-Executes the specified task (default is 'build') for a given set of BitBake files.
-It expects that BBFILES is defined, which is a space separated list of files to
-be executed.  BBFILES does support wildcards.
-Default BBFILES are the .bb files in the current directory.
-
-options:
-  --version             show program's version number and exit
-  -h, --help            show this help message and exit
-  -b BUILDFILE, --buildfile=BUILDFILE
-                        execute the task against this .bb file, rather than a
-                        package from BBFILES.
-  -k, --continue        continue as much as possible after an error. While the
-                        target that failed, and those that depend on it,
-                        cannot be remade, the other dependencies of these
-                        targets can be processed all the same.
-  -f, --force           force run of specified cmd, regardless of stamp status
-  -i, --interactive     drop into the interactive mode also called the BitBake
-                        shell.
-  -c CMD, --cmd=CMD     Specify task to execute. Note that this only executes
-                        the specified task for the providee and the packages
-                        it depends on, i.e. 'compile' does not implicitly call
-                        stage for the dependencies (IOW: use only if you know
-                        what you are doing). Depending on the base.bbclass a
-                        listtasks task is defined and will show available
-                        tasks
-  -r FILE, --read=FILE  read the specified file before bitbake.conf
-  -v, --verbose         output more chit-chat to the terminal
-  -D, --debug           Increase the debug level. You can specify this more
-                        than once.
-  -n, --dry-run         don't execute, just go through the motions
-  -p, --parse-only      quit after parsing the BB files (developers only)
-  -d, --disable-psyco   disable using the psyco just-in-time compiler (not
-                        recommended)
-  -s, --show-versions   show current and preferred versions of all packages
-  -e, --environment     show the global or per-package environment (this is
-                        what used to be bbread)
-  -g, --graphviz        emit the dependency trees of the specified packages in
-                        the dot syntax
-  -I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
-                        Stop processing at the given list of dependencies when
-                        generating dependency graphs. This can help to make
-                        the graph more appealing
-  -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
-                        Show debug logging for the specified logging domains
-  -P, --profile         profile the command and print a report

Clearly there needs to be a way to tell bitbake what files are available, and of those, which we want to execute at this time.  There also needs to be a way for each .bb to express its dependencies, both for build time and runtime.  There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>

-Two files will be written into the current working directory, <emphasis>depends.dot</emphasis> containing dependency information at the package level and <emphasis>task-depends.dot</emphasis> containing a breakdown of the dependencies at the task level. To stop depending on common depends one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs. E.g. this way <varname>DEPENDS</varname> from inherited classes, e.g. base.bbclass, can be removed from the graph.</para>

-                <para>As you may have seen in the usage information, or in the information about .bb files, the BBFILES variable is how the bitbake tool locates its files.  This variable is a space separated list of files that are available, and supports wildcards.
-                <example>
-                    <title>Setting BBFILES</title>
-                    <programlisting><varname>BBFILES</varname> = "/path/to/bbfiles/*.bb"</programlisting>
-                </example></para>
-                <para>With regard to dependencies, it expects the .bb to define a <varname>DEPENDS</varname> variable, which contains a space separated list of <quote>package names</quote>, which themselves are the <varname>PN</varname> variable.  The <varname>PN</varname> variable is, in general, by default, set to a component of the .bb filename.</para>
-                <example>
-                    <title>Depending on another .bb</title>
-                    <para>a.bb:
-    <screen>PN = "package-a"
-DEPENDS += "package-b"</screen>
-                    </para>
-                    <para>b.bb:
-    <screen>PN = "package-b"</screen>
-                    </para>
-                </example>
-                <example>
-                    <title>Using PROVIDES</title>
-                    <para>This example shows the usage of the PROVIDES variable, which allows a given .bb to specify what functionality it provides.</para>
-                    <para>package1.bb:
-    <screen>PROVIDES += "virtual/package"</screen>
-                    </para>
-                    <para>package2.bb:
-    <screen>DEPENDS += "virtual/package"</screen>
-                    </para>
-                    <para>package3.bb:
-    <screen>PROVIDES += "virtual/package"</screen>
-                    </para>
-                    <para>As you can see, here there are two different .bb's that provide the same functionality (virtual/package).  Clearly, there needs to be a way for the person running bitbake to control which of those providers gets used.  There is, indeed, such a way.</para>
-                    <para>The following would go into a .conf file, to select package1:
-    <screen>PREFERRED_PROVIDER_virtual/package = "package1"</screen>
-                    </para>
-                </example>
-                <example>
-                    <title>Specifying version preference</title>
-                    <para>When there are multiple <quote>versions</quote> of a given package, bitbake defaults to selecting the most recent version, unless otherwise specified.  If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected.  This allows the person or persons maintaining the repository of .bb files to specify their preferences for the default selected version.  In addition, the user can specify their preferences with regard to version.</para>
-                    <para>If the first .bb is named <filename>a_1.1.bb</filename>, then the <varname>PN</varname> variable will be set to <quote>a</quote>, and the <varname>PV</varname> variable will be set to 1.1.</para>
-                    <para>If we then have an <filename>a_1.2.bb</filename>, bitbake will choose 1.2 by default.  However, if we define the following variable in a .conf that bitbake parses, we can change that.
-    <screen>PREFERRED_VERSION_a = "1.1"</screen>
-                    </para>
-                </example>
-                <example>
-                    <title>Using <quote>bbfile collections</quote></title>
-                    <para>bbfile collections exist to allow the user to have multiple repositories of bbfiles that contain the same exact package.  For example, one could easily use them to make one's own local copy of an upstream repository, but with custom modifications that one does not want upstream.  Usage:</para>

-        # reason is that when the first child terminates, all processes, e.g.
-        # the second child, in the orphaned group will be sent a SIGHUP.
-        #
-        # "However, as part of the session management system, there are exactly
-        # two cases where SIGHUP is sent on the death of a process:
-        #
-        #    1) When the process that dies is the session leader of a session that
-        #        is attached to a terminal device, SIGHUP is sent to all processes
-        #        in the foreground process group of that terminal device.
-        #    2) When the death of a process causes a process group to become
-        #        orphaned, and one or more processes in the orphaned group are
-        #        stopped, then SIGHUP and SIGCONT are sent to all members of the
-        #        orphaned group." [2]
-        #
-        # The first case can be ignored since the child is guaranteed not to have
-        # a controlling terminal.  The second case isn't so easy to dismiss.
-        # The process group is orphaned when the first child terminates and
-        # POSIX.1 requires that every STOPPED process in an orphaned process
-        # group be sent a SIGHUP signal followed by a SIGCONT signal.  Since the
-        # second child is not STOPPED though, we can safely forego ignoring the
-        # SIGHUP signal.  In any case, there are no ill-effects if it is ignored.

-BitBake Shell
-
-IDEAS:
-    * list defined tasks per package
-    * list classes
-    * toggle force
-    * command to reparse just one (or more) bbfile(s)
-    * automatic check if reparsing is necessary (inotify?)
-    * frontend for bb file manipulation
-    * more shell-like features:
-        - output control, i.e. pipe output into grep, sort, etc.
-        - job control, i.e. bring running commands into background and foreground
-    * start parsing in background right after startup
-    * ncurses interface
-
-PROBLEMS:
-    * force doesn't always work
-    * readline completion for commands with more than one parameters

-    We have the following windows:
-
-        1.) Main Window: Shows what we are ultimately building and how far we are. Includes status bar
-        2.) Thread Activity Window: Shows one status line for every concurrent bitbake thread.
-        3.) Command Line Window: Contains an interactive command line where you can interact w/ Bitbake.
-
-    Basic window layout is like that:
-

-# This implements an LR parser that is constructed from grammar rules defined
-# as Python functions. The grammer is specified by supplying the BNF inside
-# Python documentation strings.  The inspiration for this technique was borrowed
-# from John Aycock's Spark parsing system.  PLY might be viewed as cross between
-# Spark and the GNU bison utility.
-#
-# The current implementation is only somewhat object-oriented. The
-# LR parser itself is defined in terms of an object (which allows multiple
-# parsers to co-exist).  However, most of the variables used during table
-# construction are defined in terms of global variables.  Users shouldn't
-# notice unless they are trying to define multiple parsers at the same
-# time using threads (in which case they should have their head examined).
-#
-# This implementation supports both SLR and LALR(1) parsing.  LALR(1)
-# support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu),
-# using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles,
-# Techniques, and Tools" (The Dragon Book).  LALR(1) has since been replaced
-# by the more efficient DeRemer and Pennello algorithm.
-#
-# :::::::: WARNING :::::::
-#
-# Construction of LR parsing tables is fairly complicated and expensive.
-# To make this module run fast, a *LOT* of work has been put into
-# optimization---often at the expensive of readability and what might
-# consider to be good Python "coding style."   Modify the code at your
-# own risk!

-    #
-    # LALR(1) parsing is almost exactly the same as SLR except that instead of
-    # relying upon Follow() sets when performing reductions, a more selective
-    # lookahead set that incorporates the state of the LR(0) machine is utilized.
-    # Thus, we mainly just have to focus on calculating the lookahead sets.
-    #
-    # The method used here is due to DeRemer and Pennelo (1982).

-"""Text progressbar library for python.
-
-This library provides a text mode progressbar. This is typically used
-to display the progress of a long running operation, providing a
-visual clue that processing is underway.
-
-The ProgressBar class manages the progress, and the format of the line
-is given by a number of widgets. A widget is an object that may
-display diferently depending on the state of the progress. There are
-three types of widget:
-- a string, which always shows itself;
-- a ProgressBarWidget, which may return a diferent value every time
-it's update method is called; and
-- a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it
-expands to fill the remaining width of the line.
-
-The progressbar module is very easy to use, yet very powerful. And
-automatically supports features like auto-resizing when available.

-    ...    # do something
-    ...    pbar.update(i+1)

-    You can also use a progressbar as an iterator:

-    >>> for i in progress(some_iterable):
-    ...    # do something
-    ...
-
-    But anything you want to do is possible (well, almost anything).
-    You can supply different widgets of any type in any order. And you
-    can even write your own widgets! There are many widgets already
-    shipped and you should experiment with them.
-
-    The term_width parameter must be an integer or None. In the latter case
-    it will try to guess it, if it fails it will default to 80 columns.
-
-    When implementing a widget update method you may access any
-    attribute or function of the ProgressBar object calling the
-    widget's update method. The most important attributes you would
-    like to access are:
-    - currval: current value of the progress, 0 <= currval <= maxval
-    - maxval: maximum (and final) value of the progress
-    - finished: True if the bar has finished (reached 100%), False o/w
-    - start_time: the time when start() method of ProgressBar was called
-    - seconds_elapsed: seconds elapsed since start_time
-    - percentage(): percentage of the progress [0..100]. This is a method.
-
-    The attributes above are unlikely to change between different versions,
-    the other ones may change or cease to exist without notice, so try to rely
-    only on the ones documented above if you are extending the progress bar.
