Run an external command on the specified DotRepr. Remember to use hSetBinaryMode on the Handle for the output function if necessary. If the command was unsuccessful, then a GraphvizException is thrown. For performance reasons, a temporary file is used to store the generated Dot code. As such, this is only suitable for local commands.
Run command against the database and return its result
runCommand1 foo = runCommand [foo =: 1]
Default to True. Should you run command line actions, set to False to skip actions whose output streams and exit code are not used. Useful for profiling the non-command portion of the build system.
