# Wrapper for custom remote provers on SystemOnTPTP
# Author: Fabian Immler, TU Muenchen
#
# Similar to the vampire wrapper, but compatible provers can be passed in the
# command line, with %s for the problemfile e.g. 
#
# ./remote Vampire---9.0 jumpirefix --output_syntax tptp --mode casc -t 3600 %s
# ./remote Vampire---10.0 drakosha.pl 60 %s
# ./remote SPASS---3.01 SPASS -Auto -SOS=1 -PGiven=0 -PProblem=0 -Splits=0 -FullRed=0 -DocProof %s
# ./remote Metis---2.1 metis --show proof --show saturation %s
# ./remote SNARK---20080805r005 run-snark %s
