2.3 Comments in `m4' input
==========================
Comments in `m4' are normally delimited by the characters `#' and
newline. All characters between the comment delimiters are ignored,
but the entire comment (including the delimiters) is passed through to
the output--comments are _not_ discarded by `m4'.
Comments cannot be nested, so the first newline after a `#' ends the
comment. The commenting effect of the begin-comment string can be
inhibited by quoting it.
`quoted text' # `commented text'
=>quoted text # `commented text'
`quoting inhibits' `#' `comments'
=>quoting inhibits # comments
The comment delimiters can be changed to any string at any time,
using the builtin macro `changecom'. Changecom, for more
information.
