Hi,
I've created a repository for testing geany-plugins conversion from svn to git here:
https://github.com/techee/geany-plugins
After consultation with Frank, it converts only the combined geany-plugins repository, not the individual plugins so the history starts 11.6.2009. This is the command I used:
svn2git https://geany-plugins.svn.sourceforge.net/svnroot/geany-plugins --trunk trunk/geany-plugins --tags tags/geany-plugins --branches branches/geany-plugins -m --authors ./authors.txt
The rest of conversion was very similar to Geany's conversion so there's not much more to describe.
Please have a good look at it and let me know if something needs to be changed. Especially please check if all the committer info is correct. There's already one suggestion from Frank to drop commit 12dcf0 - i'll do it during the final conversion.
Cheers, Jiri
