Could someone help me figure out how to get regular expressions working 
in Squeak?  I've been able to download the Regular Expression Plugin 
package using the SqueakMap Package loader.  My problem is I can't 
figure out how to make the external plugin work.

I'm using the 3.7gamma1 image and the Squeak 3.7.4Beta1 virtual machine 
for Mac.  My first question is do I need to find an external plugin 
file for regular expressions?  I saw a release note for a much older 
version of Squeak saying that regular expressions were built in now (as 
you would expect these days).  But since my VM didn't seem to know 
about a reglar expression plugin, I tried downloading a couple 
different versions and putting them in the same folder with Squeak.  
That didn't have any effect.

So what's the deal?  Do I have to compile my own external plugin?  Or 
is there a file I can just put in the same folder with Squeak?  Or is 
this functionality already part of the standard distribution?
