=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 execute any commands, remove anything, modify the
TeX Live package database or actually do anything else.
It also reports any dependencies (collections, schemes, other packages)
on the package, likely including some false positives. The person who
runs it must exercise judgement in which dependencies to remove, update,
etc.
=head1 AUTHORS AND COPYRIGHT
This script and its documentation were written for the TeX Live
