 # Script used to update the Graphite2 library in the mozilla source tree

 # This script lives in gfx/graphite2, along with the library source,

 # but must be run from the top level of the mozilla-central tree.

 # It expects to find a checkout of the graphite2 tree in a directory "graphitedev"

 # alongside the current mozilla tree that is to be updated.

 # Expect error messages from the copy commands if this is not found!

 # copy the source and headers
