 Comments
 ========
 
    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 character can be
 inhibited by quoting it.
 
    The comment delimiters can be changed to any string at any time,
 using the builtin macro `changecom'.   Changecom for more
 information.
