The author of TeXmacs speaks about 4 or 5 languages, of which English is not
his native one (although he does speak it quite well). I'm sure if C/C++
naming conventions where in German, we would all have trouble with them (I know
I would). So please remember this when you find some sort of spelling or
grammatical type error in the code.
