# Here's how the cross-compile logic breaks down ...
#  CTARGET - machine that will target the binaries
#  CHOST   - machine that will host the binaries
#  CBUILD  - machine that will build the binaries
# If CTARGET != CHOST, it means you want a libc for cross-compiling.
# If CHOST != CBUILD, it means you want to cross-compile the libc.
#  CBUILD = CHOST = CTARGET    - native build/install
#  CBUILD != (CHOST = CTARGET) - cross-compile a native build
#  (CBUILD = CHOST) != CTARGET - libc for cross-compiler
#  CBUILD != CHOST != CTARGET  - cross-compile a libc for a cross-compiler
# For install paths:
#  CHOST = CTARGET  - install into /
#  CHOST != CTARGET - install into /usr/CTARGET/

### SRC_URI ###

# This function handles the basics of setting the SRC_URI for a glibc ebuild.
# To use, set SRC_URI with:
#
#	SRC_URI="$(get_glibc_src_uri)"
#
# Other than the variables normally set by portage, this function's behavior
# can be altered by setting the following:
#
#	GENTOO_TOOLCHAIN_BASE_URI
#			This sets the base URI for all gentoo-specific patch files. Note
#			that this variable is only important for a brief period of time,
#			before your source files get picked up by mirrors. However, it is
#			still highly suggested that you keep files in this location
#			available.
#
#	BRANCH_UPDATE
#			If set, this variable signals that we should be using the main
#			release tarball (determined by ebuild version) and applying a
#			CVS branch update patch against it. The location of this branch
#			update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
#			Just like with SNAPSHOT, this variable is ignored if the ebuild
#			has a _pre suffix.
#
#	PATCH_VER
#	PATCH_GLIBC_VER
#			This should be set to the version of the gentoo patch tarball.
#			The resulting filename of this tarball will be:
#			${PN}-${PATCH_GLIBC_VER:-${GLIBC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
#
#	GLIBC_MANPAGE_VERSION
#	GLIBC_INFOPAGE_VERSION
#			The version of glibc for which we will download pages. This will
#			default to ${GLIBC_RELEASE_VER}, but we may not want to pre-generate man pages
#			for prerelease test ebuilds for example. This allows you to
#			continue using pre-generated manpages from the last stable release.
#			If set to "none", this will prevent the downloading of manpages,
#			which is useful for individual library targets.
#
