This is great, thank you sofar (and anyone else who may have worked on it).  I 
have not yet untared it in order to test/try, because I wanted to ask some 
questions upfront and give some immedate feedback

Is there any alias naming restrictions?  such as:
%SameName:SameName DifferentName
Where the alias's name is the name of an existing module (either part of that 
alias or maybe just the name of another module in the moonbase)... basicaly 
does the alias name need to be unique thoughout the moonbase?

I don't suppose you can have something like:
%Alias0:ModuleX ModuleY %Alias1
Where an alias is expanded inline.  This could cause some nasty recursion now 
that I think of it...

What is meant by this?

Can you give us an example usage in a DEPENDS file?
I'm assuming it would it be like...
depends RealModule
depends %ModuleAlias

optional_depends %AnotherModuleAlias "--enable-somethingcommon" "" "for 
something special"

Looking forward to this... It will certainly help module developers.
