In version r9941, support was added for reading region descriptions as .ini files (in addition to the existing .xml format). This page will convert .xml files into the newer .ini format. Simply copy the contents of a region's .xml file, paste it into the ".xml file" box below, and click "Convert!"
If you have a password in the .xml file, be sure to blank it out before clicking "Convert!", for your own peace of mind.
Caveats: This is a quick-and-dirty script I wrote for my own use. It doesn't do a whole lot of error checking, so its fitness for any particular purpose is not guaranteed. It was written to adhere to the RegionConfig.ini.example provided in r9950, so the results are not guaranteed if the file format changes in the future.
