It allows one to run jed scripts in batch mode with command line
parameters passed to the script.  For example, the jed and slang web
pages are constructed from a jed-script called `tmexpand`, which is
available from <http://www.jedsoft.org/jed/madewithjed.html>.

jed-script does not load your .jedrc file.  For example, put

  if (BATCH)
    message ("Running in batch-mode");

in your .jedrc file, and then run `jed --batch`.  Now create a script,
e.g., /tmp/foo that contains:

  #!/usr/bin/env jed-script
  vmessage ("jed-script running: BATCH=%d", BATCH);

and then run it using either `/tmp/foo` or `jed-script /tmp/foo`.
This test should show that your .jedrc file does not load.

If you want your jed-script to load your .jedrc file, then you must
load it from the script, e.g.,

   () = evalfile ("$HOME/.jedrc"$);   % slang-2 syntax

If you want to run a pure slang script that makes use of only slang
intrinsics then slsh should be used.

I hope this help clarify things a bit.
Thanks,
