+# options set different build-time options for catalyst. Some examples are:
+# autoresume = Attempt to resume a failed build, clear the autoresume flags with
+#	the -a option to the catalyst cmdline.  -p will clear the autoresume flags
+#	as well as your pkgcache and kerncache
+#	( This option is not fully tested, bug reports welcome )
+# bindist = enables the bindist USE flag, please see package specific definition,
+#	however, it is suggested to enable this if redistributing builds.
+#	This optional USE flag is normally cleaned from the make.conf file on
+#	completion of the stage.  For a non-cleaned version,
+#	use sticky-config also (see below)
+# ccache = enables build time ccache support
+# distcc = enable distcc support for building. You have to set distcc_hosts in
+#	your spec file.
+# icecream = enables icecream compiler cluster support for building
+# keepwork = Prevents the removal of the working chroot path and any autoresume
+#	files or points.
+# kerncache = keeps a tbz2 of your built kernel and modules (useful if your
+#	build stops in livecd-stage2)
+# pkgcache = keeps a tbz2 of every built package (useful if your build stops
+#	prematurely)
+# preserve_libs = enables portage to preserve used libs when unmerging packages
+#	(used on installcd-stage2 and stage4 targets)
+# seedcache = use the build output of a previous target if it exists to speed up
+#	the copy
+# snapcache = cache the snapshot so that it can be bind-mounted into the chroot.
+#	WARNING: moving parts of the portage tree from within fsscript *will* break
+#	your cache. The cache is unlinked before any empty or rm processing, though.
+# sticky-config = enables the code that will keep any internal 'catalyst_use' flags
+#	added to the USE= for building the stage.  These ae usually added for legal
+#	or specific needs in building the the early stage.  Mostly it is the
+#	'bindist' USE flag option that is used for legal reasons, please see its
+#	specific definition.  It will also keep any /etc/portage/package.*
+#	files or directories.

+# source_matching specifies how catalyst will match non-specific file names
+# if the filename is not found as an exact match.
+# ie: a filename without the extension specified.  "/path/to/foo"
+#
+# possible values are:
+#   "strict" meaning if more than one file of that name is present with any
+#            file extension, then it will raise an exception.
+#   "loose"  meaning it will search for an existing filename with an added
+#            extension from an ordered list of extensions determined from the
+#            decompressor_search_order specification in the spec file or (default)
+source_matching="strict"

+# as usual and get cleaned every time a stage build is restarted.

+# this feature requires a pretty large tmpfs ({open,libre}office needs ~8GB to build)
