       e_axfilter 1.9 "Sourenee"

       This problem applies SinE-like goal-directed filters to a problem
       specification to generate reduced problem specifications that are
       easier to handle for the prover, but still are likely to contain the
       necessary axioms for a proof (if one exists). The program reads a
       problem specification and a filter specification, and produces one
       reduced specifiation for each filter given. Note that while all input
       formats (LOP, TPTP-2 and TPTP-3 are supported, output is only and
       automatically supported in TPTP-3, and the default input format is
       TPTP-3. Also note that unlike most of the other tools in the E
       distribution, this program does not support pipe-based input and
       output, since it uses file names generated from the input file name and
       filter names to store the different result files



              Print a short description of program usage and options.



              Print the version number of the prover. Please include this with
              all bug reports (if any).



              Verbose comments on the progress of the program. This differs
              from the output level (below) in that technical information is
              printed to stderr, while the output level determines which
              logical manipulations of the clauses are printed to stdout. The
              short form or the long form without the optional argument is
              equivalent to --verbose=1.

       -o <arg>


              Redirect output into the named file (this affects only some
              output, as most is written to automatically generated files
              based on the input and filter names.



              Equivalent to --output-level=0.

       -l <arg>


              Select an output level, greater values imply more verbose

       -f <arg>


              Specify the filter definition file. If not set, the system will
              uses the built-in default.



              Print the filter definition in force.


              Parse input in E-LOP, not the default TPTP-3 format.


              Equivalent to --lop-in.


              Parse TPTP-2 format instead of E-LOP (but note that includes are
              handled according to TPTP-3 semantics).


              Equivalent to --tptp-in.


              Synonymous with --tptp-in.


              Synonymous with --tptp-in.


              Parse TPTP-3 format instead of E-LOP (Note that TPTP-3 syntax is
              still under development, and the version in E may not be fully
              conforming at all times. E works on all TPTP 5.4.0 FOF and CNF
              input files (including includes).


              Equivalent to --tstp-in.


              Synonymous with --tstp-in.
