My name is Clemens Koppensteiner; I'm a graduate student in mathematics; I live near Chicago, though I am a citizen of Austria; my main use of (La)TeX is writing mathematical documents (and illustrating them).

Any TeX code of mine that I publish on http://tex.stackexchange.com/ I hereby place in the public domain to the extent governable by law, except when stated otherwise in the corresponding answer. Explicitly, I place it under the CC0.
