18.2 Conditional Not Commands
=============================

You can specify text to be included in any output format _other_ than a
given one with the '@ifnot...' environments:

     @ifnotdocbook ... @end ifnotdocbook
     @ifnothtml ... @end ifnothtml
     @ifnotinfo ... @end ifnotinfo
     @ifnotplaintext ... @end ifnotplaintext
     @ifnottex ... @end ifnottex
     @ifnotxml ... @end ifnotxml

The '@ifnot...' command and the '@end' command must appear on lines by
themselves in your actual source file.

  If the output file is being made in the given format, the region is
_ignored_.  Otherwise, it is included.

  There is one exception (for historical compatibility): '@ifnotinfo'
text is omitted for both Info and plain text output, not just Info.  To
specify text which appears only in Info and not in plain text, use
'@ifnotplaintext', like this:

     @ifinfo
     @ifnotplaintext
     This will be in Info, but not plain text.
     @end ifnotplaintext
     @end ifinfo

  The regions delimited by these commands are ordinary Texinfo source as
with '@iftex', not raw formatter source as with '@tex' (Note: Raw
Formatter Commands).
