+"""
+Generate a driver/library benchmark based on DFA/PTA traces.
+
+Usage:
+PYTHONPATH=lib bin/generate-dfa-benchmark.py [options] <pta/dfa definition>
+
+generate-dfa-benchmarks reads in a DFA definition and generates runs
+(i.e., all words accepted by the DFA up to a configurable length). Each symbol
+corresponds to a function call. If arguments are specified in the DFA
+definition, each symbol corresponds to a function call with a specific set of
+arguments (so all argument combinations are present in the generated runs).
+
+Options:
+--depth=<depth> (default: 3)
+    Maximum number of function calls per run
+
+--instance=<name>
+    Override the name of the class instance used for benchmarking
+
+--sleep=<ms> (default: 0)
+    How long to sleep between function calls.
