[TLPKG]... =head1 OPTIONS The standard options B<-q>, B<-v>, and B<-logfile>=I are accepted; see the C function in L for details. =head1 DESCRIPTION B merely prints Subversion commands to remove TeX Live packages from the source repository, e.g., when a package becomes obsolete or merged. It does not actually run any commands, remove anything, or change the TeX Live package database or anything else. No dependency or other checking is done. It also does not remove the given package from any collection(s) where it is present, although it reports any collections and schemes that have dependencies on the package. =head1 AUTHORS AND COPYRIGHT This script and its documentation were written for the TeX Live distribution (L) and both are licensed under the GNU General Public License Version 2 or later. =cut ### Local Variables: ### perl-indent-level: 2 ### tab-width: 2 ### indent-tabs-mode: nil ### End: # vim:set tabstop=2: #
