Option to disable description checking

[KendallHarter]

It's too specific: one such example is that doc strings MUST end in '.' and not any other valid punctuation, such as '!'.
Also there are legitimate uses for wanting to start with a lowercase letter (e.g. true or false)

[JacobFischer]

I agree on the other punctuation.

I can't think of when we'd want to start with a lowercase letter. The doc strings are used for all clients, and in some "true" is True (python), while in others it is true (JavaScript). People will understand what we mean and I'd rather uniformity in the doc strings.

[KendallHarter]

Can't you just run toupper on the doc strings before passing them to the clients?
No need to force manual uppercase, and would also help with internationalization (although I'm not sure how much of an issue that is)
