[cse491] Making twill scripts executable scripts

[C. Titus Brown]

Hi all,

if, as the first line of your twill script file, you put

#! /usr/bin/env twill-sh

and then 'chmod +x' your script, you will then be able to run the twill
script directly from the command line.

The '/usr/bin/env' looks for twill-sh in your $path shell variable.  You
could also put in the path directly to twill-sh,

#! /user/ctb/install/bin/twill-sh

but that would then be entirely specific to the CSE install; the first
approach will work on any machine where twill-sh is in your path.

cheers,
