-
-This library is really just two files: 'tinyprintf.h' and 'tinyprintf.c'.
-
-They provide a simple and small (+400 loc) printf functionality to
-be used in embedded systems.
-
-I've found them so useful in debugging that I do not bother with a
-debugger at all.
-
-They are distributed in source form, so to use them, just compile them
-into your project.
-
-Two printf variants are provided: printf and the 'sprintf' family of
-functions ('snprintf', 'sprintf', 'vsnprintf', 'vsprintf').
-
-The formats supported by this implementation are:
-'c' 'd' 'i' 'o' 'p' 'u' 's' 'x' 'X'.
-
-Zero padding and field width are also supported.
-
-If the library is compiled with 'PRINTF_SUPPORT_LONG' defined, then
-the long specifier is also supported. Note that this will pull in some
-long math routines (pun intended!) and thus make your executable
-noticeably longer. Likewise with 'PRINTF_LONG_LONG_SUPPORT' for the
-long long specifier, and with 'PRINTF_SIZE_T_SUPPORT' for the size_t
-specifier.
-
-The memory footprint of course depends on the target CPU, compiler and
-compiler options, but a rough guesstimate (based on a H8S target) is about
-1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack space.
-Not too bad. Your mileage may vary. By hacking the source code you can
-get rid of some hundred bytes, I'm sure, but personally I feel the balance of
-functionality and flexibility versus  code size is close to optimal for
-many embedded systems.
-
-To use the printf, you need to supply your own character output function,
-something like :
-
-void putc ( void* p, char c)
-{
-    while (!SERIAL_PORT_EMPTY) ;
-    SERIAL_PORT_TX_REGISTER = c;
-}
-
-Before you can call printf, you need to initialize it to use your
-character output function with something like:
-
-init_printf(NULL,putc);
-
-Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc',
-the NULL (or any pointer) you pass into the 'init_printf' will eventually be
-passed to your 'putc' routine. This allows you to pass some storage space (or
-anything really) to the character output function, if necessary.
-This is not often needed but it was implemented like that because it made
-implementing the sprintf function so neat (look at the source code).
-
-The code is re-entrant, except for the 'init_printf' function, so it is safe
-to call it from interrupts too, although this may result in mixed output.
-If you rely on re-entrancy, take care that your 'putc' function is re-entrant!
-
-The printf and sprintf functions are actually macros that translate to
-'tfp_printf' and 'tfp_sprintf' when 'TINYPRINTF_OVERRIDE_LIBC' is set
-(default). Setting it to 0 makes it possible to use them along with
-'stdio.h' printf's in a single source file. When
-'TINYPRINTF_OVERRIDE_LIBC' is set, please note that printf/sprintf are
-not function-like macros, so if you have variables or struct members
-with these names, things will explode in your face.  Without variadic
-macros this is the best we can do to wrap these function. If it is a
-problem, just give up the macros and use the functions directly, or
-rename them.
-
-It is also possible to avoid defining tfp_printf and/or tfp_sprintf by
-clearing 'TINYPRINTF_DEFINE_TFP_PRINTF' and/or
-'TINYPRINTF_DEFINE_TFP_SPRINTF' to 0. This allows for example to
-export only tfp_format, which is at the core of all the other
-functions.
-
-For further details see source code.
