This is a very small collection of software projects that I have contributed to, or in some cases, created. Most of the software projects that match either of those descriptions were originally created before there was such a thing as GitHub (in some cases before Git itself), and so have not yet found there way here.
The collection will grow, however, as I work on my own new or existing software projects (or new contributions to others') and integrate them into a Git-aware environment. I will, for example, in the near future, make a point to add (the admittedly also small, older, and incomplete collection of) software projects and contributions from my vanity web server.
