The --script is described in the emacs manual, but no example is
provided.  Adding it to Worg (maybe with a two-stage explanation:
trivial "Hello World" example, followed by an org-specific example)
is a good idea.

For contributing to Worg, see the "Maintenance of Worg" section:

Note that you could do this even before --script was invented:

  emacs --batch -l /path/to/somefile.el

is exactly equivalent to the --script invocation of somefile.el, which
in turn is more or less[fn:1] equivalent to stuffing the above command
line into a bash script file, making *that* executable and running it.
The --script method is a bit more convenient but it is just "syntactic
sugar".

[fn:1] There is an extra fork/exec of bash in this method, but that's about it.
