This question already has an answer here:
I just started to learn LaTeX, and I have to do some documentation with it.
However, the guy editing the TeX manuscript of the documentation before me didn't pay attention to word wrapping, so long lines aren't wrapped at all at the moment.
What is the best way to do auto-word-wrap (based on the margin, if possible)?
Improve/Edit: I use verbatim, and the word wrap I mean is the output-file
