This site has been created on a FreeBSD system. HTML was written directly in a text editor, heavily relying on G-Cows' features, of course.
Text files have been edited with GNU Emacs; if you already use it, you know it's much more than an editor; otherwise, you can read something about it at www.gnu.org/software/emacs/emacs.html.
Graphics have been created with The Gimp (www.gimp.org).
