DOpus and AREXX scripts, HOW TO?

[XDelusion]

I was looking for some simple tools to extract DMS files, etc when I ran across this script for DOPUS:

http://www.aminet.net/search.php?query=undms

As you can see, there are no instructions on how to set this up, which is the case with many of the various scripts I've found on Aminet.

How do I set this up, how do I make AREXX auto run at boot time, where do I find out more about AREXX in the first place?

Thankx!

Thank you very much!

Good luck with those kitties!
