`@w'{TEXT}: Prevent Line Breaks
===============================

  `@w{TEXT}' outputs TEXT and prohibits line breaks within TEXT.

  You can use the `@w' command to prevent TeX from automatically
hyphenating a long name or phrase that happens to fall near the end of a
line.

     You can copy GNU software from @w{@samp{ftp.gnu.ai.mit.edu}}.

     *Caution:* Do not write an `@refill' command at the end of a
     paragraph containing an `@w' command; it will cause the paragraph
     to be refilled and may thereby negate the effect of the `@w'
     command.
