X.\" The News macro package
X.\"
X.\" This is the macro package that is used to format news documents. It
X.\" was written because many sites do not have one of the -mm or -ms pack-
X.\" ages that the documents use. This is NOT compatible with EITHER, but
X.\" (I hope) will become the standard for all news documents (man pages
X.\" excepted, since everyone seems to have -man.)
X.\"
X.\" This package was written using only the "NROFF/TROFF Users' Guide",
X.\" and therefore if you can run NROFF/TROFF, you can legitimately use
X.\" this package. However, because NROFF/TROFF are proprietary programs,
X.\" I cannot place this package in the public domain. This should not
X.\" matter, because if you legitimately have NROFF/TROFF, you have the
X.\" documentation; if not, you can't run off the documentation anyway.
X.\"
X.\" This package may be circulated freely with the news documentation; it
X.\" may not be sold, but is to be distributed with the unformatted news
X.\" documents. However, the name of the author and the place at which it
X.\" was written (in the author's own time, of course) are not to be
X.\" removed from the package regardless of how it is modified or altered.
X.\" Further, please do not distribute this package if you make any changes
X.\" because I don't want to get bug reports of macros I haven't written;
X.\" if you have a goodie you want me to add, send it to me and we'll talk.
X.\" (I really do like feedback!) I'd really appreciate your cooperation.

X.\" version 1.0 September 28, 1985 mab@riacs.arpa
X.\" initial version
X.\" version 1.1 October 25, 1985 mab@riacs.arpa
X.\" fixed an incredibly obscure footnote bug (that occurred twice in
X.\" the news documentation!) which put footnoted words on one page
X.\" and the footnote on the next if the word was in the next-to-last
X.\" or last line; commented it, and generally cleaned up
X.\" Version 1.2 October 27, 1985 mab@riacs.arpa
X.\" Added a few more comments and a check to keep footnotes lined up
X.\" with the bottom margin.
X.\" Version 1.3 February 12, 1986 mab@riacs.arpa
X.\" Added an error check to catch unmatched ef's and ed's
X.\" Version 1.4 December 29, 1986 mab@riacs.edu
X.\" Changed footnote for ux, pd, and vx macros and added a string
X.\" for rg ("Registered Trademark")
X.\" Version 1.5 January 2, 1989 Matt.Bishop@dartmouth.edu
X.\" Minor modifications for nroff compatibility
X.\" Version 1.6 March 15, 1989 Matt.Bishop@dartmouth.edu
X.\" ..!bear.dartmouth.edu!bishop
X.\" Fixed a bug in footnote handling (again, sigh ...) This one
X.\" occurred when the the "fo" trap position was reset just beneath
X.\" the current line; the footnote overflow trap would kick in and
X.\" never be closed.

X..
X.\" **********
X.\" these are the footnote macros
X.\" here's an overview:
X.\" Footnotes are processed in environment #1, which is initialized
X.\" at the bottom of this package. When "fn" is called, nroff/troff
X.\" switches to this environment. The body of the footnote is saved
X.\" in the diversion "tf" (for "temporary footnote"), so you will
X.\" NEVER spring a trap during the first reading of a footnote. When
X.\" "ef" ("end footnote") is called, the diversion is closed. If
X.\" this is the first footnote on the page (ie, the number register
X.\" "fc" is 1), and the footnote height (plus the height of 1 line)
X.\" crosses the bottom margin, you get the footnoted word on one
X.\" page and the footnote on the other. In this case we just call
X.\" "fo" manually (taking case it cannot be re-invoked on the same
X.\" page!) If this situation does not occur, we just adjust the
X.\" footer trap's position upwards (we'll get to how far in a min-
X.\" ute); if this puts the trap above the current line, we reposi-
X.\" tion the trap just beneath the current line to be sure of trig-
X.\" triggering it once the current line is forced out.
X.\" To reposition the footer trap, we proceed as follows. Because
X.\" the trap may be sprung in the middle of a line, it is possible
X.\" that the footnote will not fit on the page (regardless of where
X.\" on the page the footnoted word occurs -- really!) if we move the
X.\" trap up by the size of the footnote diversion "tf". So, we
X.\" fudge things a little bit -- for the first footnote on each page
X.\" we move the footer trap up 1 extra line ("line" being 1v in env-
X.\" ironment #0). Unless the point size and vertical spacing are
X.\" increased between the first footnote and the footer trap's being
X.\" sprung, this will keep the footnotes on the same page as the
X.\" footnoted word. But as there may be now as much as 1v of space
X.\" between the footnote and the bottom margin, which looks HIDEOUS,
X.\" we use the number register "fs" to mark where the footer trap
X.\" would REALLY go, and just space to it when it comes time to put
X.\" out the footnotes.
X.de fd \" dump footnotes
X.nr gs 1v \" get a measure of 1 line in env #0
X.ev 1 \" switch to footnote environment
X.nr gs +2v \" min of 2 lines of footnotes
X. \" if the number register ns > 0,
X. \" the last text line may contain a
X. \" footnote that is too big to fit;
X. \" this checks for such a note and
X. \" if so, forces the footnote into
X. \" the "fy" diversion that carries
X. \" it onto the next text page

X. \" is that there is no way to force
X. \" NROFF/TROFF to invoke a macro at
X. \" the end of each line. At times,
X. \" the trap boundary will not match up
X. \" with the bottom of a line, so the
X. \" "fo" trap which is set at 2320 may
X. \" not be triggered until 2340 -- and
