See module 'pg' for more info about the existing Erlang mechanism.

  Hello everybody,

  Robert and I have made a scripting interface to erlang. This is a
simple one pass "load and go" Erlang scripting interface - so now you can
use Erlang directly as a scripting language and won't need all this
"erl -noshell -pa ...." stuff :-)

 Read all about it on:

 http://www.bluetail.com/~joe/escript.html

 Have fun.

  /Joe

Thank you. I like it very much - and it solved a script-hacking
problem I just faced ;-)

I had to do one small fix (add -sasl errlog_type error)
to get the generated escript script work to my liking:

#!/bin/sh
erl -sasl errlog_type error -pa
/home/epkbeti/cvscheckout/netsimbase/bin/escript-1.0 -noshell -s escript
go $0 $*

  Here is an improved version of escript - offering

        a) Luke's hack (posted earlier)
        b) Interpreted and *compiled* scripts

  For slow scripts you might like to compile the module using the

        -mode(compile).

  Option.

  See the examples in factorial1 and factorial2
