I need to use custom filters, so I need to convert some long log4j.properties files to log4j.xml.
Is anyone aware of a tool to do this, or willing to contribute one
I needed to do this as well, but couldn't find a tool. Migrating by hand dozens of log4j.properties was not a palatable option. So, I bashed together a tool that can do it and released it for others to use.

It's a bit rough but did the trick for the log4j properties I gave it, so any problems log them on the issue tracker. Hope you find it useful.
