G'day,
I just noticed in TFM for 0.15 that the section "Supported systems" is somewhat dated. Might be time to give it a little refresh, as certainly Geany compiles and runs successfully on Fedora 7/8/9 now too, and I dare say it also works on Debian Lenny. Also, your website page on third party packages lists many more distros it apparently compiles on.
