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'.  Note: Changecom for more
information.
