Put PCWSTY.TEX into subdirectory \pctex\texinput (or equivalent) before
use. All other files should go in directory \pcwrite. Use PC-WRITE's PR
program to print file PCWRITEX.DOC to disk file PCWRITEX.TEX, then run
TeX on that file to generate documentation. Development history is in
file PCWRITEX.UPD. If you do not have TeX, rename PCWRITEX.DOC to
PCWRITEX.TXT and print it using the PR program to get plain ASCII.
