Anyone contemplating using github to host their library be warned that they are deprecating the downloads section in 90 days (starting 11 December 2012). I've got a couple of such libraries and would like to continue to use github. These libraries have a relatively low volume of take-up and are probably for the more technically inclined anyway. Any bang goes the idea of switching processing distro from googlecode to github, unless there is an autobuild!
