For all those who emailed me ( especially the nasty ones ) suggesting
that I'm slamming Python in favor of Perl ( which I know well enough
to know, I don't like it )  by most I mean:

sh,csh,bash,tcsh,zsh ( and OK Perl )

ones that I seem to remember it being in but am not quite sure:

ksh, awk.

Ones that I'm sure don't do it
Python, sed ( and I'm not sure about sed, it's just not likely to be
there ).
