+#  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.

+#  CBUILD = CHOST = CTARGET    - native build/install

+#  (CBUILD = CHOST) != CTARGET - libc for cross-compiler
+#  CBUILD != CHOST != CTARGET  - cross-compile a libc for a cross-compiler

+### 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 ${GENTOO_TOOLCHAIN_BASE_URI}.
+#			Just like with SNAPSHOT, this variable is ignored if the ebuild
+#			has a _pre suffix.
+#
+#	PATCH_VER
+#	PATCH_GLIBC_VER
+#			This should be set to the version of the gentoo patch tarball.
+#			The resulting filename of this tarball will be:
+#			glibc-${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.
