+AIGER is a format for And-Inverter Graphs (AIGs).
+See http://fmv.jku.at/aiger/ for details.
+
+AIGER is used in the Hardware Model Checking Competition (HWMCC),
+therefore all solvers competing in the competition have to support
+the format.
+
+The example in this directory is using super_prove as solver. Check
+http://downloads.bvsrc.org/super_prove/ for the lates release. (See
+https://bitbucket.org/sterin/super_prove_build for sources.)
+
+The "demo.sh" script in this directory expects a "super_prove" executable
+in the PATH. E.g. extract the release to /usr/local/libexec/super_prove
+and then create a /usr/local/bin/super_prove file with the following
+contents (and "chmod +x" that file):
+
+	#!/bin/bash
+	exec /usr/local/libexec/super_prove/bin/super_prove.sh "$@"
+
+The "demo.sh" script also expects the "z3" SMT2 solver in the PATH for
+converting the witness file generated by super_prove to VCD using
+yosys-smtbmc. See https://github.com/Z3Prover/z3 for install notes.
