Comments in file

You can insert comments into the LaTeX input (*.tex) file. Anything following a percent sign (`%`) until the end of the line is ignored by the LaTeX processor.

In fact, the `%` ends a line without generating a space; an end-of-line in LaTeX input is normally equivalent to a space. Thus, for example, it allows one to split a word over lines without inserting a break. For example

       this is an extr%
           ordinarily long word

would produce "this is an extraordinarily long word" with no breaks. However, a command cannot be split over lines this way.
