17	# one abi in ${MULTILIB_ABIS}. You might want to use this like	29	# one abi in ${MULTILIB_ABIS}. When has_multilib_profile returns true, that

19	# 'multilib' use flag are removed from portage	31	# a package only for multilib or not multilib.

21	# is_final_abi:
22	# Return true if ${ABI} is the final abi to be installed (and thus we are
23	# on our last run through a src_* function.

27
28	# get_abi_order:
29	# Return a list of the ABIs we want to install for with
30	# the last one in the list being the default.
31
32	# get_all_libdirs:
33	# Returns a list of all the libdirs used by this profile. This includes
34	# those that might not be touched by the current ebuild and always includes
35	# "lib".
36
37	# get_libdir:
38	# Returns the libdir for the selected ABI. This is backwards compatible
39	# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
40	# to determine where to install shared objects (ex: /usr/$(get_libdir))
41
42	# get_abi_var <VAR> [<ABI>]:
43	# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
44	#
45	# get_abi_CFLAGS:
46	# get_abi_CDEFINE:
47	# get_abi_LIBDIR:
48	# Aliases for 'get_abi_var CFLAGS', etc.
49
50	# get_ml_incdir [<include dir> [<ABI>]]
51	# include dir defaults to /usr/include
52	# ABI defaults to ${ABI} or ${DEFAULT_ABI}
53	#
54	# If a multilib include dir is associated with the passed include dir, then
55	# we return it, otherwise, we just echo back the include dir. This is
56	# neccessary when a built script greps header files rather than testing them
57	# via #include (like perl) to figure out features.
58
59	# prep_ml_includes:
60	# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
61	# We can install them in different locations for each ABI and create a common
62	# header which includes the right one based on CDEFINE_${ABI}. If your
63	# package installs ABI-specific headers, just add 'prep_ml_includes' to the
64	# end of your src_install(). It takes a list of directories that include
65	# files are installed in (default is /usr/include if none are passed).
66	#
67	# Example:
68	# src_install() {
69	# ...
70	# prep_ml_includes /usr/qt/3/include
71	# }
72
73	# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
74	# If you need more control than prep_ml_includes can offer (like linux-headers
75	# for the asm-* dirs, then use create_ml_includes. The firs argument is the
76	# common dir. The remaining args are of the form <symbol>:<dir> where
77	# <symbol> is what is put in the #ifdef for choosing that dir.
78	#
79	# Ideas for this code came from debian's sparc-linux headers package.
80	#
81	# Example:
82	# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
83	# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
