Where do I report errors, submit patches, ask questions, etc?
The answer to all of these is whaley at cs.utsa.edu. Please note that error reports need to be accompanied by inputs and arguments that demonstrate the error. Bug reports that do not have a method of confirming the bug will be ignored. As to asking question, please remember I’m not payed for this, so make sure your question is not answered in the supplied documentation (this FAQ, the user’s guide, example index, etc). If you’d like to see a feature added to extract, explaining why you need it and how it would be useful is definitely recommended.
