		13	# has_multilib_profile:
		14	# Return true if the current profile is a multilib profile and lists more than
		15	# one abi in ${MULTILIB_ABIS}. You might want to use this like
		16	# 'use multilib \|\| has_multilib_profile' until all profiles utilizing the
		17	# 'multilib' use flag are removed from portage
		18
		19	# is_final_abi:
		20	# Return true if ${ABI} is the final abi to be installed (and thus we are
		21	# on our last run through a src_* function.
		22
		23	# number_abis:
		24	# echo the number of ABIs we will be installing for
		25
		26	# get_install_abis:
		27	# Return a list of the ABIs we want to install for with
		28	# the last one in the list being the default.
		29
		30	# get_all_abis:
		31	# Return a list of the ABIs supported by this profile.
		32	# the last one in the list being the default.
		33
		34	# get_all_libdirs:
		35	# Returns a list of all the libdirs used by this profile. This includes
		36	# those that might not be touched by the current ebuild and always includes
		37	# "lib".
		38
		39	# get_libdir:
		40	# Returns the libdir for the selected ABI. This is backwards compatible
		41	# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
		42	# to determine where to install shared objects (ex: /usr/$(get_libdir))
		43
		44	# get_abi_var <VAR> [<ABI>]:
		45	# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
		46	#
		47	# get_abi_CFLAGS:
		48	# get_abi_CDEFINE:
		49	# get_abi_LIBDIR:
		50	# Aliases for 'get_abi_var CFLAGS', etc.
		51
		52	# get_ml_incdir [<include dir> [<ABI>]]
		53	# include dir defaults to /usr/include
		54	# ABI defaults to ${ABI} or ${DEFAULT_ABI}
		55	#
		56	# If a multilib include dir is associated with the passed include dir, then
		57	# we return it, otherwise, we just echo back the include dir. This is
		58	# neccessary when a built script greps header files rather than testing them
		59	# via #include (like perl) to figure out features.
		60
		61	# prep_ml_includes:
		62	# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
		63	# We can install them in different locations for each ABI and create a common
		64	# header which includes the right one based on CDEFINE_${ABI}. If your
		65	# package installs ABI-specific headers, just add 'prep_ml_includes' to the
		66	# end of your src_install(). It takes a list of directories that include
		67	# files are installed in (default is /usr/include if none are passed).
		68	#
		69	# Example:
		70	# src_install() {
		71	# ...
		72	# prep_ml_includes /usr/qt/3/include
		73	# }
		74
		75	# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
		76	# If you need more control than prep_ml_includes can offer (like linux-headers
		77	# for the asm-* dirs, then use create_ml_includes. The firs argument is the
		78	# common dir. The remaining args are of the form <symbol>:<dir> where
		79	# <symbol> is what is put in the #ifdef for choosing that dir.
		80	#
		81	# Ideas for this code came from debian's sparc-linux headers package.
		82	#
		83	# Example:
		84	# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
		85	# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
		86
		87	# get_libname [version]
		88	# returns libname with proper suffix {.so,.dylib} and optionally supplied version
		89	# for ELF/MACH-O shared objects
		90	#
		91	# Example:
		92	# get_libname libfoo ${PV}
		93	# Returns: libfoo.so.${PV} (ELF) \|\| libfoo.${PV}.dylib (MACH)
