https://tex.stackexchange.com/landing/r/digest?cta=question&id=534

Often assignments (or even papers) have a word count limit. That is not a big deal when using Word, but I don't know how to do that using LaTeX. My solution has been so far to compile the document and ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=8625
