# 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
# repoistories.
#
# 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.

# Do nothing if this is inherited, as it's for BBCLASSEXTEND
