This is the 'booleforce' SAT solver. To compile the solver, run './configure' first and then issue 'make'. This should build an optimized version of the solver 'booleforce' and the trace checker 'tracecheck'. Further options to './configure', which for instance allow 'proof generation' or debugging, are described in the command line option summary of configure which can be obtained by './configure -h'. For usage of the solver as a library consider the API described in 'booleforce.h'. Only the library 'libbooleforce.a' needs to be linked. Armin Biere, JKU Linz, October 2010.
