The TPTP  (Thousands  of Problems  for Theorem  Provers)  Problem Library  is a
library  of  test problems for  automated theorem proving  (ATP)  systems.  The 
principal motivation for the TPTP  is to support the testing and evaluation  of 
ATP systems,  to help ensure that  performance results  accurately reflect  the
capabilities of the ATP system being considered. 

TPTP v8.2.0 is now available at:
    http://www.tptp.org
The TPTP-v8.2.0.tgz file  contains the  library,  including utilities and basic
documentation. Full documentation is online at:

+ In SyntaxBNF:
  - Separated <ntf_connective> into <nhf_connective> and <nxf_connective>.
  - <nhf_key_pair> defined as <thf_definition>, and similarly <nxf_key_pair>
    defined as <txf_definition>.
  - Removed nhf_connective and <nxf_connective>, added <ntf_short_connective>
    as a unary connective.
