EPCLEXTRACT

NAME

epclextract - manual page for epclextract 2.6

SYNOPSIS

epclextract [options] [files]

DESCRIPTION

epclextract 2.6

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

Options

	-h
	--help

Print a short description of program usage and options.

	-V
	--version

Print the version number of the program.

	-v
	--verbose[=<arg>]

Verbose comments on the progress of the program. The short form or the long form without the optional argument is equivalent to --verbose=1.

	-f
	--fast-extract

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 protocoll.

	-C
	--forward-comments

Pass comments found in the input through to the output while reading input.

	-c
	--competition-framing

Print special "begin" and "end"comments around the proof object, as required by the CASC MIX* class.

	-n
	--no-extract

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.

--tstp-out

Print proof protocol in TSTP syntax (default is PCL).

--tptp3-out

Synonymous with --tstp-out.

	-o <arg>
	--output-file=<arg>

Redirect output into the named file.

	-s
	--silent

Equivalent to --output-level=0.
