Synopsis [The main() procedure.]
Description [This procedure compiles into a stand-alone program for
DAG-aware rewriting of the AIGs. A BLIF or PLA file to be considered
for rewriting should be given as a command-line argument. Implementation
of the rewriting is inspired by the paper: Per Bjesse, Arne Boralv,
"DAG-aware circuit compression for formal verification", Proc. ICCAD 2004.]
