uclean
UCLEAN(1) Command reference UCLEAN(1) NAME
uclean - remove redundant files from upstream source packages SYNOPSIS
uclean FILE [ NEWFILE... ] DESCRIPTION
Uclean is an attempt to automate the "cleanup" procedure that can be needed for some package upstream tarballs. It will try to unpack it, remove cruft like CVS directories, .svn directories and forgotten object files. Then it will recreate the tarball, using the highest compression ratio. The resulting file is either stored under the same name (the old one is renamed) or as a new file if you specify it as the last argument. SEE ALSO
