my point was that if, for the wrapper to work, each script has to be
modified to add the comment indicating the "language", then why not just
use the proper "#!/usr/bin/env language" line, and avoid the wrapper
altogether? most of the scripts which are used in TL bin directories are
already checked anyway.
