For this reason I had to move check listing and some error diagnostic after actually running the tool. This might not be a too big usability issue though, since it was not possible to list the available checkers without input files anyways. However it would be harder to improve on that after this patch is applied.
A clarification regarding the current state: a file name on the command line is currently needed to find a directory to read configuration from. The file doesn't have to exist as the analysis isn't run when we just want to list the checks.

As for the requirement to run the analysis in order to get the list of checks: I don't think it's a good idea. Do you just need this to parse the command line?
