=head1 NAME
tl-merge-tlpdb - merge a tlpdb into another
=head1 SYNOPSIS
tl-merge-tlpdb [--save|--help|-?|--quiet|-q] I<from-tlpdb-root>
=head1 DESCRIPTION
This script merges the tlpdb which is located in the usual place within
the hierarchy of I<from-tlpdb-root> into the tlpdb from the hierarchy where
the script is located. The script has to be located in the root of the
tlnet hierarchy I<into> which another tlpdb should be merged.
No comparison of revisions whatsoever is done, all package are simply added,
overriding already present package or adding new ones.
The script does I<not> copy the actual containers from
I<from-tlpdb-root>C</archive>, this has to be done manually.
The script checks whether important options as set in the tlpdbs agree,
most importantly the format of the container and splitting of doc and
src files.
=head1 OPTIONS
=over 4
=item B<-save>
Default operation is to write the generated tlpdb to stdout, from where
it can be captured and compared with the existing one. If one does not
want to take this extra safety step, providing this options overwrites
the tlpdb immediately.
=item B<-nocleanup>
In case of B<-save> being present, by default, the script updates
the C<texlive.tlpdb.md5> file with the correct value, and also
removes the file C<texlive.tlpdb.xz> to facilitate easy integration
into a web service.
Giving the option B<-nocleanup> prevents the script from executing
these steps.
=item B<-quiet>, B<--quiet>, B<-q>
Do not give any informative messages besides errors.
=item B<-help>, B<--help>, B<-h>, B<-?>
Display this help and exit.
=back
=head1 EXAMPLES
Assuming that the script is located in the root of a tlnet checkout, one
can merge the packages of another tlnet-like repository into it with
tl-merge-tlpdb -save /path/to/tlptexlive
Usage of an URL for the argument is also possible
tl-merge-tlpdb -save http://tug.org/~preining/tlptexlive/
