http://forum.tinycorelinux.net/index.php?topic=7397.0This topic above has relatively detailed info for 6u21; right now the repo contains relatively old versions (back from late January this year), and I'm unsure of the working status of them. (after checking the topic by helander) After 9 months or so, I think that the tcz in the repo should be updated, given the available information in various discussions (the one I linked is not the only one). I myself lack the skills to do so, but again, people are out there who could do it, no?
On an off-topic note, first post in Extensions Requests board~!
