cvs modules

[Tate Austin]

Hey, I am trying to write a module hierarchy for cvs; I have a root directory with a series of directories I want to exclude, it looks like this:

 

logic /maindirectory &exunchanged &exskins &exinclude

 

exunchanged, exskins, exinclude are all exclusion aliases (ex: exunchanged -a !unchanged-directory)  So am I forbidden to put multiple modules on this line?  How can I exclude directories from a module?
