Overfull "hboxes"
=================

  TeX is sometimes unable to typeset a line without extending it into
the right margin.  This can occur when TeX comes upon what it
interprets as a long word that it cannot hyphenate, such as an
electronic mail network address or a very long title.  When this
happens, TeX prints an error message like this:

     Overfull \hbox (20.76302pt too wide)

(In TeX, lines are in "horizontal boxes", hence the term, "hbox".  The
backslash, `\', is the TeX equivalent of `@'.)

  TeX also provides the line number in the Texinfo source file and the
text of the offending line, which is marked at all the places that TeX
knows how to hyphenate words.  *Note Catching Errors with TeX
Formatting: Debugging with TeX, for more information about typesetting
errors.

  If the Texinfo file has an overfull hbox, you can rewrite the sentence
so the overfull hbox does not occur, or you can decide to leave it.  A
small excursion into the right margin often does not matter and may not
even be noticeable.

  However, unless told otherwise, TeX will print a large, ugly, black
rectangle beside the line that contains the overfull hbox.  This is so
you will notice the location of the problem if you are correcting a
draft.

  To prevent such a monstrosity from marring your final printout, write
the following in the beginning of the Texinfo file on a line of its own,
before the `@titlepage' command:
