/**
* This script is meant to be used as a command-line tool, or else as the target of a custom action within
* Quanta
* The script will get the contents of a file which is the generated output of a PHPMyAdmin SQL Schema export, and change the
* format of the table defintion 'headings' into the H2 heading format suitable for posting into MediaWiki
* This process creates easy to navigate and reference SQL schema files in the wiki
* The exact tag output by this script (<sql> or <source lang=sql>) must correlate with the MediaWiki extension you use to get syntax highlighting
* In any case, you need to have a GeSHi syntax highlighting extension active in your MediaWiki installation.
*
* @Usage
* php /path/to/pma2wiki.php /some/pma-schema.sql
