Setup

1: download a perl interpreter

You can get a windows binary over here.
If that link is bad try here. (grab the Windows 5.8.x AS package)
As a last resort, search for ActivePerl at activestate.com.

If you aren't a windows user, check out this site.

2: fire it up

If everything is installed correctly you should now have the command 'perl' available to you.
If you do, then running this at a command line perl -le "print 'hello world'" should output hello world.

3: get my module

If you are using ActivePerl then running ..
ppm install http://scumc.sourceforge.net/SCUMC.ppd
.. at a command prompt should automatically install the latest version available.

If that doesn't work, or you aren't using ActivePerl, download it at my sourceforge project page.

3: dry run

So, now let's make sure we got everything. At a command prompt, type perl -MSCUMC -e ""

If you don't receive any errors then we should be good to go.

4: get winmpq

This is optional and for windows only.
If you want to work with compressed files, I need external help from WinMPQ.
You can get WinMPQ at ShadowFlare's Realm
Make sure to put it in your PATH.
