-/**
- * Import data from a UseModWiki into a MediaWiki wiki
- * 2003-02-09 Brion VIBBER <brion@pobox.com>
- * Based loosely on Magnus's code from 2001-2002
- *
- * Updated limited version to get something working temporarily
- * 2003-10-09
- * Be sure to run the link & index rebuilding scripts!
- *
- * Some more munging for charsets etc
- * 2003-11-28
- *
- * Partial fix for pages starting with lowercase letters (??)
- * and CamelCase and /Subpage link conversion
- * 2004-11-17
- *
- * Rewrite output to create Special:Export format for import
- * instead of raw SQL. Should be 'future-proof' against future
- * schema changes.
- * 2005-03-14
