In the end of 90's I looked for a method building GUIs for some special command line programs. My fellow students want to use these command line programs :-)
So I went to the library and couldn't decide me between Perl/Tk and Ousterhoud. According to Murphy's Law I took Perl/Tk. After realizing that my scripts unreadable by me I converted to TCL in 2001.
I sometimes write answers in the German TCL/Tk forum
