Delete your working copy of the file if the release
succeeds. If this flag is not given your files will
remain in your working directory.
Warning: The release command uses
`rm -r module' to delete your file. This
has the very serious side-effect that any directory
that you have created inside your checked-out sources,
and not added to the repository (using the add
command; see add) will be silently deleted---even
if it is non-empty!
