Move TCL script files -- Step 1 of 2:
- Move src/target/{interface,target,board,test}/ into src/tcl/ - Remove existing rules in src/Makefile.am and src/target/Makefile.am. - Add Makefile.am handling of *.cfg and *.tcl files in top Makefile.am: - Add dist-hook to include such files under src/tcl in the distribution. - Add install-data-hook to install contents of '$(top_srcdir)/src/tcl/'. - Add uninstall-hook to remove the installed script files. - Change paths to (un)install script files in '$(pkgdatadir)/scripts'. git-svn-id: svn://svn.berlios.de/openocd/trunk@1918 b42882b7-edfa-0310-969c-e2dbd0fdcd60
