 #!/usr/bin/perl
 
 # This perl script read stdin and write on stdout. It shall be an XML language file.
 #
 # * If the name of the language is 'HTML', then it creates the language 'PHP (HTML)'
 #   which shall be used for PHP hl.
 #
 # * If the name of the language is something else (say '*'), it creates the language '*/PHP'.
 #   This new language is the same as the old one, but is able to detect PHP everywhere.
 #
 # This script will correctly set extensions & mimetype, and will replace
 # <IncludeRules context="##*"> by <IncludeRules context="##*/PHP">
 #
 # Generated languages need a language named 'PHP/PHP', which shall take care of PHP hl itself
 # and which will be called every time something like <?php is encountred.
 #
 # This script also supports Twig and does the same as for PHP.
