9.1.6 '@verb'{CHARTEXTCHAR}
---------------------------

Use the '@verb' command to print a verbatim sequence of characters.

  Like LaTeX's '\verb' command, the verbatim text can be quoted using
any unique delimiter character.  Enclose the verbatim text, including
the delimiters, in braces.  Text is printed in a fixed-width font:

     How many @verb{|@|}-escapes does one need to print this
     @verb{.@a @b.@c.} string or @verb{+@'e?`{}!`\+} this?

produces

     How many @-escapes does one need to print this
     @a @b.@c string or @'e?`{}!`\ this?

  This is in contrast to '@samp' (see the previous section), '@code',
and similar commands; in those cases, the argument is normal Texinfo
text, where the three characters '@{}' are special, as usual.  With
'@verb', nothing is special except the delimiter character you choose.

  The delimiter character itself may appear inside the verbatim text, as
shown above.  As another example, '@verb{...}' prints a single
(fixed-width) period.

  It is not reliable to use '@verb' inside other Texinfo constructs.  In
particular, it does not work to use '@verb' in anything related to cross
referencing, such as section titles or figure captions.
