Converting greymatter to b2evolution

I was converting Y's blog from greymatter to b2evolution. There is no ready-made conversion. The trick was to export the greymatter blog to movable type export format. Then use the b2evolution movable type format import to import the blog entries.

I'm using the latest one-month-old b2evolution and of course... the MT importer was broken. Had to make some fixes to it. Also it didn't really read the MT format, so had to change that a little. Unfortunately took more time than I wished, but I succeeded. Converted 100 posts and all the comments, plus deleted all the spam from greymatter since there was no spam control on that blog.

I've decided to write this down so other people can do it more easily, hopefully. Here

I guess b2evolution is not using a regression unit test set with cruisecontrol. Then this wouldn't have happened :)
