=head1 NAME
check-depend-consistency - check that all dependencies exist as packages
=head1 SYNOPSIS
check-depend-consistency [OPTION]...
=head1 OPTIONS
Only the standard options B<-help> and 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
Check that all C<depend> statements in all TeX Live packages
(collections, schemes, and normal packages) refer to existing packages.
Also check that every package is a dependency of at least one collection.
These checks are made according to the tlpdb that is within the
hierarchy from which this script is invoked; the actual file tree is not
inspected.
=head1 AUTHORS AND COPYRIGHT
