Subject: Re: Initialize a variable in an extended class

Yes! That is indeed clever. I overlooked
the extend method.

I'm probababy going to be kicking myself for
not figuring out the rest of the solution,
but I'll ask anyway:

    What's the best way to share TAGS between
    this module and my main module?

Also:
   Where is the best place to read about
   modules. I have yet to grok their essence,
   as shown by this example and my HTree
   question!
