Works like a charm and it's even in the doc under C.1.4 Excluding
directories.  Now that I know what terminology (removing verses excluDing) I
should be searching for, it was easy to find in the doc.

Try excluding stuff in your modules def's using the shebang notation 
(that is "!").  I do stuff like this on very large modules, excluding 
things nested in the tree that I don't want in various checkouts.

Define one module to be the 'universe'.  I have developed the habit of 
explicitly naming this module 'xxxxuniverse', where xxxx is the overall 
product or project name.  Then, selectively define what you want in each 
of the environments.  Ignore the physical structure of the repository 
for this exercise.  Just scratch together a quick Wish List.  i.e. 
"Module Foo should be dirA, dirB, dirF and dirG but nothing else. 
Repeat this exercise for each environment you need to create.

Then methodically add corresponding def's to the modules file for each 
of the above.  You may have to tweak the def's a few times before you 
grok this technique (I certainly did).  Here's an example:

# in the defs below, the shebang is used as an exclude modifier. jbminn

   -a !engineering/autobuild !engineering/products !engineering/tools 
!engineering/buildsystem engineering

   -a !engineering/autobuild !engineering/buildsystem 
!engineering/products !engineering/quality engineering

autobuild -a !engineering/products !engineering/quality 
!engineering/tools   engineering
