Usage: `basename "$0"` /path/to/vim/source/x.y [ACTION+]
       `basename "$0"` x.y [ACTION+]

In second case, x.y is searched in "standard" download locations.

Final directory must be of form major.minor (e.g., 7.2).

Valid ACTIONs are:
  download          - use rsync to download Vim sources
  unpack            - unpack Vim sources below CWD
  configure         - configure Vim with standard build options
  build             - build Vim and create binary tarball

If no ACTIONs are specified, defaults to unpack configure build.
