1. 22x22 in *toolbar.xrc is fine. It is replaced with the proper string for the selected resolution. I guess we could change it to something more meaningful.
2. update31 should all be removed. I'll do it soon.
3. I don't have any 22x22 folder. I guess someone with svn should remove the empty folders. Git just removes them, I guess, without telling svn.
4. FortranProject is maintained by darmar.
