For some stupid reason SCO never incorporated this convention into either
their csh or Bourne shell.  It would be nice to tag awk, perl, sed, etc.
scripts this way.

The SCO csh looks at the first line of a script.  If it starts with '#' it's
a csh script.  Therefore, your "#!/bin/sh" causes this to be run by the csh!
I put a single line containing only a colon at the start of each of
my Bourne shells scripts, and they run fine out of the csh or Bourne shell.

Running a csh script from a Bourne shell is messier.  You have to explicitly
run the csh, as in "csh script_name".
