=head1 NAME
tl-compare-tlpdbs - compare two tlpdbs
=head1 SYNOPSIS
tl-compare-tlpdbs [I<option>]... <TLPDB1> [<TLPDB2>]
=head1 OPTIONS
=over 4
=item B<-help>
Print this documentation and exit.
=back
The standard options B<-q>, B<-v>, and B<-logfile>=I<file> are also
accepted; see the C<process_logging_options> function in
L<TeXLive::TLUtils> for details.
=head1 DESCRIPTION
This program compares two tlpdbs. If two arguments are given both
have to refer to a .tlpdb file and the two tlpdbs will be compared.
If only one argument is given then the tlpdb from the tree of this
program itself is compared with the tlpdb given on the command line.
The comparision reports revision differences, and if the revision are
the same, differences in the file lists.
