+# ROX-0install eclass Version 1
+
+# Created by Jim Ramsay (lack@gentoo.org) to ease installation of ROX desktop
+# applications and integrate this with zeroinstall-injector
+# (http://0install.net)
+
+# These variables are only used inside functions, and so may be set anywhere in
+# the ebuild:
+#
+# ZEROINSTALL_STRIP_REQUIRES - this flag, if set, will force the local
+#    zeroinstall feed to have all its 'requires' directives stripped out
+# LOCAL_FEED_SRC - The ebuild-supplied native feed, for those packages which do
+#    not already contain one.  By default we check for ${APPNAME}.xml and
+#    ${APPNAME}/${APPNAME}.xml
+
+# This is an extension of rox.eclass
+inherit rox

+# Does all the 0install local feed magic you could want:
+#   - Parses the input file to get the interface URI
+#   - Edits the input file and installs it to the final location
+#   - Installs a local feed pointer
+#
+# Environment variables:
+#  ZEROINSTALL_STRIP_REQUIRES - If set, strips all 'requires' sections from the XML
+#                            on editing.  Default: Not set
+#
+# 0install_native_feed <src> <destpath>
+#  src   - The XML file we will edit, install, and point at
+#  path  - The path where the implementation will be installed 
+#          IE, the final edited xml will be at <path>/<basename of src>
