#
# gegl may now (since 0.0.22) use sse or mmx for accelerated calculations
#

# The workshop directory (and thus the `workshop' use flag) is where
# experimental stuff is built into.  You shouldn't need it unless you're
# developing on gegl yourself.  Maybe therefore it should only exist in
# the svn ebuild?
