# the purpose of this magic is to pull in the latest runtime files for vim
# we start withe theruntime provoded by the tarballs and compare MD5s against
# the latest runtime
# if this fails we look in the local source cache if they have been fetched
# for an earlier build and compare those MD5 files
# if this fails, we fetch the stuff from online and store it in the local src
# cache.
