+#
+# Other than the variables normally set by portage, this function's behavior
+# can be altered by setting the following:
+#
+#	SNAPSHOT
+#			If set, this variable signals that we should be using a snapshot
+#			of gcc from ftp://sources.redhat.com/pub/gcc/snapshots/. It is
+#			expected to be in the format "YYYY-MM-DD". Note that if the ebuild
+#			has a _pre suffix, this variable is ignored and the prerelease
+#			tarball is used instead.
+#
+#	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 ${GENTOO_TOOLCHAIN_BASE_URI}.
+#			Just like with SNAPSHOT, this variable is ignored if the ebuild
+#			has a _pre suffix.
+#
+#	PATCH_VER
+#	PATCH_GCC_VER
+#			This should be set to the version of the gentoo patch tarball.
+#			The resulting filename of this tarball will be:
+#			gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
+#
+#	PIE_VER
+#	PIE_GCC_VER
+#			These variables control patching in various updates for the logic
+#			controlling Position Independant Executables. PIE_VER is expected
+#			to be the version of this patch, and PIE_GCC_VER the gcc version of
+#			the patch:
+#			An example:
+#					PIE_VER="8.7.6.5"
+#					PIE_GCC_VER="3.4.0"
+#			The resulting filename of this tarball will be:
+#			gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
+#
+#	SPECS_VER
+#	SPECS_GCC_VER
+#			This is for the minispecs files included in the hardened gcc-4.x
+#			The specs files for hardenedno*, vanilla and for building the "specs" file.
+#			SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
+#			the gcc version of the patch.
+#			An example:
+#					SPECS_VER="8.7.6.5"
+#					SPECS_GCC_VER="3.4.0"
+#			The resulting filename of this tarball will be:
+#			gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
+#
+#	HTB_VER
+#	HTB_GCC_VER
+#			These variables control whether or not an ebuild supports Herman
+#			ten Brugge's bounds-checking patches. If you want to use a patch
+#			for an older gcc version with a new gcc, make sure you set
+#			HTB_GCC_VER to that version of gcc.

+This is the file .../info/dir, which contains the topmost node of the
+Info hierarchy.  The first time you invoke Info you start off
+looking at that node, which is (dir)Top.
+
+File: dir	Node: Top	This is the top of the INFO tree
+
+  This (the Directory node) gives a menu of major topics. 
+  Typing "q" exits, "?" lists all Info commands, "d" returns here,
+  "h" gives a primer for first-timers,
+  "mEmacs<Return>" visits the Emacs topic, etc.
+
+  In Emacs, you can click mouse button 2 on a menu item or cross reference
+  to select it.
+
+* Menu: The list of major topics begins on the next line.
