312# header which includes the right one based on CDEFINE_${ABI}. If your
313# package installs ABI-specific headers, just add 'prep_ml_includes' to the
314# end of your src_install(). It takes a list of directories that include
315# files are installed in (default is /usr/include if none are passed).
316#
317# Example:
318# src_install() {
319# ...

363# @USAGE: <include_dir> <symbol_1>:<dir_1> [<symbol_2>:<dir_2>...]
364# @DESCRIPTION:
365# If you need more control than prep_ml_includes can offer (like linux-headers
366# for the asm-* dirs, then use create_ml_includes. The firs argument is the
367# common dir. The remaining args are of the form <symbol>:<dir> where
368# <symbol> is what is put in the #ifdef for choosing that dir.
369#
370# Ideas for this code came from debian's sparc-linux headers package.
371#
372# Example:
373# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
374# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64

376# Warning: Be careful with the ordering here. The default ABI has to be the
377# last, because it is always defined (by GCC)
