=head1 NAME
tl-update-containers - create, update, or remove TL containers
=head1 SYNOPSIS
tl-update-containers [OPTION]...
=head1 OPTIONS
=over 8
=item B<-containerdir> I<containerdir>
The location to find the previously generated containers;
default is C<./tlpkg>. If this is changed so that the containers appear
in a different directory on the net, then you need to also
specify C<<--netarchive>> to C<install-tl.pl> or they will not be found.
=back
The standard options C<-help> and C<-debug> are also accepted.
See the tlpfiles documentation for details.
The format of the containers and the splitting off of source and
documentation files are controlled by the TLPDB options in the
pseudo-package C<00texlive.config>. See the documentation for TLPDB.
=head1 DESCRIPTION
The B<tl-update-containers> program compares the revision of each
package found in C<containerdir> with the revision of the same package
in C<texlive.tlpdb>, found relative to this script. Where the latter is
newer (i.e., a higher number), the container(s) for the package are
updated. Where the container(s) do not exist, they are created. When
the package no longer exists in tlpdb, the container(s) are removed.
