The logic-TPTP package

For information about the TPTP format, see http://www.cs.miami.edu/~tptp/.

Components:

Parser (parse)
Exporter (toTPTP)
Pretty-printer (pretty)
QuickCheck instances (generation of random formulae)
diff : Get a "formula" which represents the differences between two given formulae (equal subexpressions are truncated; so are the subexpressions of subexpressions whose heads already differ)

Tests passed:

For randomly generated formulae, parse . toTPTP == id
For all files in the TPTP (v 5.2.0) distribution's Problems subtree which don't match the regex "^(thf|tff)(", parse . toTPTP . parse == parse

Not yet implemented: The new thf and tff formula types.
