Following is a general description of the software included
here. This software can be compiled and linked on any VMS
system version 5.0 or greater (and version 4.X systems with
minor modifications). The binaries can be patched,
linked or run on any VMS system version 5.2 or later (maybe 5.0).

DVIOUT is a program, written in C, that interprets a Device-
Independent (DVI) file produced by programs such as TeX and
produces output on a particular output device. It has a number of
special features, accessible through command line options and
through "special" commands. It is designed
to handle more than one type of output device, and adding
device protocols to its repertoir of devices is a relatively
easy, but not trivial, task. It currently supports the Tektronix
4014 and standard PostScript output devices at 300, 400, 600 and
1200 dpi, with the Apple LaserWriter being a special case. It
should work with the DEC LN03R printer. Additional information
is contained in the file "dviout.txt".

It is assumed the user of this software understands the TeX
system and the requirements for pixel files, as well as the
facilities of the VMS operating system. The TeX and METAFONT
systems are quite complex, and successful integration of this
software to a specific site requires an in-depth understanding
of these systems, although most of the nitty-gritty details are
not needed to successfully install this software.

It is the author's hope that users of various high resolution
graphics output devices being used with TeX will develop new
drivers for specific output devices and provide a copy of the
driver software so that it can be incorporated into the distribution
of the DVIOUT software.

The auxiliary program QUERYLW produces TFM files for the native
Apple LaserWriter fonts. It conducts an "interactive" dialog with the
LaserWriter, and converts the information thus obtained into font
metric property list files. Because the metric information for the
LaserWriter is proprietary to Apple (or Adobe), it cannot be supplied.
However, the QUERYLW program can generate it for you. No documentation
for this program is provided, other than that present or implied within
the source files and example command files.

The auxiliary program PSFONT generates PostScript fonts from the fonts
generated by METAFONT and used by TeX. These fonts can then be sent
to the printer to remain permanently resident (or until the printer is
turned off). DVIOUT can recognize whether these fonts are present
through the site-modifiable options file for the printer. Using the
downloaded TeX fonts speeds up DVIOUT and results in the print job
completing quite a bit faster as well, although more memory is consumed
in the printer.

The ALWSMB program is a print symbiont specifically written for the
Apple LaserWriter. It can send DVIOUT's output PostScript files to
the LaserWriter, or any PostScript file from any source. It can handle
downloading of permanently resident fonts by using a special "exitserver"
mode. Additional information on the symbiont is in the files
"smbreadme.1st" and "symbiont.txt".

This software is furnished "as is". Although considerable effort
has been expended to make this software correct and reliable, no
warranty is implied; the author disclaims any obligation or
liability for damages, including but not limited to special,
indirect, or consequential damages arising out of or in connection
with the use or performance of this software.
