Hi,
I just migrated my diary from tDiary 2.0 (another popular Ruby
blogging engine, especially in Japan) to Typo, and I created a script
to convert the categories/articles/comments. It’s available at:

Feel free to bundle it in the upstream distribution if you want.
Typo is BTW an impressive application, keep the good work!
