Submitted-by: clewis at ecicrl.uucp (Chris Lewis)

I'm really sorry that Psroff 2.0 itself hasn't been posted.
It's been sitting in Rich's queue for comp.sources.unix since
July.  I'm going to see if I can get it out through comp.sources.misc
in a timely fashion, if not, I'll just post it thru alt.sources.

If you do wish to followup to this article, please ensure that
your posting goes to comp.text - since I've moved to Ottawa, I've
been paying LD charges for my news, and I've not been receiving
any of the sources groups.

This is (almost) a trivial patch.  When Psroff gets posted in its
entirety, it will be at THIS level (PL4).

    This is official patch 04 for Psroff 2.0.
    Please apply it by:
	cd <psroff source directory>
	patch -N -p < <this file>

./man/troff2ps.1.S	Documented optimizer (-Z & -W)
./debug.c		trailing spaces.
./utils/Makefile	forgot catconv
./defs.h		PL4 & NODECMD for systems without uuname -l.
./dt.c			trailing spaces.
./utils.c		NODECMD

  options allow you to specify page X and Y offsets respectively.
  The value should be a number with a valid troff scale factor.
  Eg: ``-O.463i''.
+ .P
+ The
+ .B -Z
+ and
+ .B -W
+ options controller the optimizer.
+ If the
+ .B -Z
+ option is specified, the backends attempt to coalesce strings of
+ characters into one drawing request.
+ Without this option,
+ .B troff2
+ draws words by positioning each letter separately.
+ The optimizer can reduce the size of the output file by factors of 3 or
+ more, and printer speeds similarly, particularly in Postscript.
+ This option is disabled in ditroff-output-mode - it's up to the
+ ditroff filter to optimize.
+ The
+ .BI -W directory
+ allows you to specify where the width tables are, by default they
+ are "/usr/lib/font/\fItype\fP", where \fItype\fP is the driver
+ type specified by the
+ .B -T
+ option.
+ This option is useful if you've moved the width directory somewhere
+ else, or the final directory name is different from the
+ .B -T
+ value.
+ See psrofflib entry "ops" for an example.
+ The
+ .B -W
+ option is ignored unless
+ .B -Z
+ is specified.
+ .P
+ The optimizer is quite good, but it is known that columns of text separated
+ by a leader made up of periods can fool it.
+ At the present time, it is unknown whether it's a width table or
+ printer or troff wierdness.
  .SH "SPECIAL REQUESTS"
  .BI troff2 xx
  supports a number of additional features over and above bare
