The TPTP Domain Structure
-------------------------
The domain structure of the TPTP is depicted below,  with counts of the numbers
of problems and  versions in each domain.  The prefixes  name subdirectories in 
the Problems directory, and prefix the problem names in that directory.

                                                     Domain    # of Problems
     Field             Subfield                      Prefix  Abst / Vers / Gen
