Here at https://github.com/svenk you find a couple of open source software I published. Since I typically used to commit
with <user@computer-name> credentials, my contribution activity is sparse.
See also my gists at https://gist.github.com/svenk. I also publish my work over there at Bitbucket: https://bitbucket.org/svek/
Head over to my personal website at https://svenk.org/ for more links.
