IMPORTANT NOTE:

This package contains the source of the Tex-program, written in C.
It does not contain fonts or macros. It is intended as a performance
upgrade, or a porting aid for people who already have the Tex distribution
tape. The whole Tex distribution is much too large to put on the net.

How to install this TeX-port on Unix (or Xenix) systems:

1) "unshar" the shell archives.
	You should then have the following files:

Makefile
README
ext.pc3.c
externs.h
h00vars.pc3.h
pc3.lib.h
texpaths.h
virtex.c
virtex.pool
virtex1.c
virtex10.c
virtex11.c
virtex12.c
virtex13.c
virtex14.c
virtex2.c
virtex3.c
virtex4.c
virtex5.c
virtex6.c
virtex7.c
virtex8.c
virtex9.c

2) for each virtex* file make a link to a file initex* with the same
   suffix (e.g. "ln virtex1.c initex1.c")...
   if desired, do the same for triptex.

3) verify the options in the Makefile, for your Unix system.

4) type "make initex" and "make virtex", optionally also "make triptex".

5) run initex:	(this is exactly as for the Berkeley Pascal version)
	$ initex
	plain \dump
	...
	$ virtex
	&plain \read 0 to\blort
	\blort=  press control-\ to dump core
	$ undump tex virtex core

6) The standard Tex distribution contains undump for Berkeley Unix.
   An undump for SCO-Xenix 2.2 will be posted on the net separately.

PERFORMANCE
===========

It is never possible to give exact figures of what performance to expect.
Roughly speaking the performance is up to 100% faster than the Berkeley
Pascal version, 5% faster than C-tex and 10% faster than Microtex (the
latter on an IBM-AT).

This means about 2 seconds per page for Tex and 4 seconds for Latex, on
a 1 Mips machine, 5 seconds for Tex and 10 for Latex on an IBM-AT
(without 80287).
