+# Class for use in BBCLASSEXTEND to make it easier to have a single recipe that
+# can build both stable tarballs and snapshots from upstream source
+# repositories.
+#
+# Usage:
+# BBCLASSEXTEND = "devupstream:target"
+# SRC_URI_class-devupstream = "git://git.example.com/example"
+# SRCREV_class-devupstream = "abcdef"
+#
+# If the first entry in SRC_URI is a git: URL then S is rewritten to
+# WORKDIR/git.
+#
+# There are a few caveats that remain to be solved:
+# - You can't build native or nativesdk recipes using for example
+# devupstream:native, you can only build target recipes.
+# - If the fetcher requires native tools (such as subversion-native) then
+# bitbake won't be able to add them automatically.
