+=head1 NAME
+
+parse-texcatalogue-keywords - parse the experimental TeX Catalogue
+
+=head1 SYNOPSIS
+
+parse-texcatalogue-keywords [--input ....] [--output ...] [--help|-h|-?]
+
+=head1 DESCRIPTION
+
+This program parses the XML data dump of the experimental new
+TeX Catalogue which includes various characterizations of packages,
+into keywords, functionalities, and classifications.
+
+It dumps this data in a textual representation of a perl hash, which
+can very easily be read back into a perl program.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-input>

+
+where to write the data dump to, defaults to STDOUT.
+
+=item B<-help>, B<-h>, B<-?>

+=head1 FORMAT OF THE DATA DUMP
+
+The following Perl expression explain in which way the data is saved into
+the dumped hash:
+
+ $taxonomy{'by-package'}{'keyword'}{$package} = [ $kwi, $kwii,...];
+
+List of keywords
+
+ $taxonomy{'by-package'}{'primary'}{$package} = $primchar;
+
+Scalar containing the primary characterization.
+
+ $taxonomy{'by-package'}{'secondary'}{$package'} = $secchar;
+
+Scalar containing the secondary characterization.
+
+ $taxonomy{'by-package'}{'functionality'}{$package} = [ $bfi, $bfii, ...];
+
+List of functionalities.
+
+Both the characterizations and functionalites are themselves subdivided into
+levels by the string separator " > " (without the quotes). To make
+these information more accessible the data is presented in a reverse
+way, too:
+
+ $taxonomy{'by-taxonomy'}{'keyword'}{$keyword} = [ $pkg1, $pkg2, ...];
+
+List of packages with that keyword
+
+ $taxonomy{'by-taxonomy'}{'primary'}{$level1}{$level2}...{'_packages_'} = [ $pkg1, $pkg2, ...];
+ $taxonomy{'by-taxonomy'}{'secondary'}{$level1}{$level2}...{'_packages_'} = [ $pkg1, $pkg2, ...];
+ taxonomy{'by-taxonomy'}{'functionality'}{$level1}{$level2}...{'_packages_'} = [ $pkg1, $pkg2, ...];
+
+The B<_packages_> is literal and contains the list of packages for all the
+previous levels.
+
+The following code allows to read back the array into the hash referenced
+by C<$taxonomy> (attention, in this code this is a B<reference> to a hash!
+ my $taxonomy;
+ my $taxtext = `cat $path_to_data_dump`;
+ no strict "vars";
+ eval "$taxtext";
+ use strict "vars";
+ return $taxonomy;
