# get_all_libdirs:
# Returns a list of all the libdirs used by this profile.  This includes
# those that might not be touched by the current ebuild and always includes

# get_libdir:
# Returns the libdir for the selected ABI.  This is backwards compatible
# and simply calls get_abi_LIBDIR() on newer profiles.  You should use this
# to determine where to install shared objects (ex: /usr/$(get_libdir))

# get_abi_var <VAR> [<ABI>]:
# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
#
# get_abi_CFLAGS:
# get_abi_CDEFINE:
# get_abi_LIBDIR:
# Aliases for 'get_abi_var CFLAGS', etc.

# get_ml_incdir [<include dir> [<ABI>]]
# include dir defaults to /usr/include
# ABI defaults to ${ABI} or ${DEFAULT_ABI}
#
# If a multilib include dir is associated with the passed include dir, then
# we return it, otherwise, we just echo back the include dir.  This is
# neccessary when a built script greps header files rather than testing them
# via #include (like perl) to figure out features.

# prep_ml_includes:
# Some includes (include/asm, glibc, etc) are ABI dependent.  In this case,
# We can install them in different locations for each ABI and create a common
# header which includes the right one based on CDEFINE_${ABI}.  If your
# package installs ABI-specific headers, just add 'prep_ml_includes' to the
# end of your src_install().  It takes a list of directories that include
# files are installed in (default is /usr/include if none are passed).
#
# Example:
# src_install() {
#    ...
#    prep_ml_includes /usr/qt/3/include
# }

# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
# If you need more control than prep_ml_includes can offer (like linux-headers
# for the asm-* dirs, then use create_ml_includes.  The firs argument is the
# common dir.  The remaining args are of the form <symbol>:<dir> where
# <symbol> is what is put in the #ifdef for choosing that dir.
#
# Ideas for this code came from debian's sparc-linux headers package.
#
# Example:
# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64

# get_libname [version]
# returns libname with proper suffix {.so,.dylib} and optionally supplied version
# for ELF/MACH-O shared objects
#
# Example:
# get_libname libfoo ${PV}
# Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
