+# This script generates, from an input R1CS configuration, a proving
+# key and a verification key. It then uses libsnark to generate a
+# proof for the R1CS, given a satisfying assignment. Finally, it runs
+# the libsnark verifier on the resulting proof file and reports the
+# result.
+
+# All libsnark output is redirected to LOG.
+
+# Exit codes:
+# 1: not enough arguments
+# 2: a required file didn't exist
+# 3: key-generation failed
+# 4: proof-generation failed
+# 5: verification failed
