Help for PS files
PS files are files printable on
PostScript printers.
The printout from a PS file looks the same like that
from the
corresponding DVI file.
But, since PS files take much more time
to download than DVI
files,
DVI files should be
generally preferred
to PS files.
PS files in this collection were
produced from the same TeX source
files the book has been typeset
from.
