How to use it

! Word boundaries are inferred from spaces, hyphens and existing capital letters.
! Acronyms are lowercased, so API becomes api in camelCase.

Does it handle acronyms like HTTP?

It splits them into words, so HTTPResponse becomes httpResponse rather than keeping HTTP intact.

Can it convert a whole document?

Yes, but title case will capitalise every word including short ones.

Is the text sent anywhere?

No.
