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

317# src_install() {

363# @DESCRIPTION:
364# If you need more control than prep_ml_includes can offer (like linux-headers
365# for the asm-* dirs, then use create_ml_includes. The firs argument is the
366# common dir. The remaining args are of the form <symbol>:<dir> where
367# <symbol> is what is put in the #ifdef for choosing that dir.
368#
369# Ideas for this code came from debian's sparc-linux headers package.

371# Example:
372# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
373# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
