This would _not_ be "perlscript.pl" itself. This is the shell-script, and
it's not called ".pl".
In other words, you'd put this as ~/bin/cg-xxxx, and then "perlscript.pl"
wouldn't be in the path at all, it would be in some separate install
directory.
But hey, if people want to be safe for bad installations, add the extra
line. Shell won't care ;)
