[Boost-build] GLOB for directories

I assume GLOB returns all files, including directories. How can I then 
test for a directory as opposed to a non-directory file in a GLOB result 
? I need to GLOB from a directory but only find those files that are 
themselves directories. I could not find a rule which does this in some 
module and I am hoping I just missed the module in which such 
functionality exists.
