epclextract [options] [files]


epclextract 0.41

Read an PCL2 protocol and print the steps necessary for proving the clauses in "proof", "final", or "extract" steps.

Print a short description of program usage and options.
Print the version number of the program.
Verbose comments on the progress of the program. The short form or the long form without the optional argument is equivalent to --verbose=1.
Do a fast extract. With this option the program understands only a subset of PCL and assumes that all "proof" and "final" steps are at the end of the protokoll.
Print special "begin" and "end"comments around the proof object, as requiered by the CASC MIX* class.
Don't extract, print back all steps (actually, it treats all steps as proof steps). Useful as a syntax checker, or if you want to convert PCL to TSTP with the next option.
Print proof protocol in TSTP syntax (default is PCL).
-o <arg>
Redirect output into the named file.
Equivalent to --output-level=0.
