Why did I get the error "Unable to read entire line"?

If you get this error, it generally indicates that you have really long lines in your latex file.

If you're using Emacs, you can easily fix this in one of two ways:

• Press M-Q in each paragraph.
• Hit ctrl-space at the beginning of your text. Go to the end of your text and type M-x fill-region
