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).
