=head1 NAME
tl-fix-container-infos - updates or adds size and checksum for containers
=head1 SYNOPSIS
tl-fix-container-infos [I<option>]...
=head1 OPTIONS
=over 4
=item B<-dry-run|-n>
Don't write anything.
=item B<-location> I</container/dir>
The directory of containers to be updated, requiring
I</container/dir>C</tlpkg/texlive.tlpdb>, usually with a previous set of
containers to be compared against; default is C<.>.
=item B<-no-setup>
Does not try to setup the various programs, but uses I<xz> and I<tar>
from the current path.
=item B<--help>
Display this documentation and exit.
=item B<--version>
Display version information 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.
The format of the containers and the splitting of source and
documentation files are controlled by the TLPDB options in the
pseudo-package C<00texlive.config>. See L<TeXLive::TLPDB>.
=head1 DESCRIPTION
This program adds or updates {,src,doc}container{size,checksum}
directive entries for packages found in the TL location. Only packages
without a previous C<containerchecksum> entry are updated.
