=head1 NAME
tlprm - remove a TeX Live package
=head1 SYNOPSIS
tlprm [OPTION]... [TLPKG]...
=head1 OPTIONS
The standard options B<-q>, B<-v>, and B<-logfile>=I<file> are
accepted; see the C<process_logging_options> function in
L<TeXLive::TLUtils> for details.
=head1 DESCRIPTION
B<tlprm> 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<http://tug.org/texlive>) and both are licensed under the
GNU General Public License Version 2 or later.
