CTAN, the Comprehensive TeX Archive Network, is the
repository of TeX and LaTeX documentation. The archive is
mirrored in numerous places, but the UK node is at
<http://www.tex.ac.uk>.
DVItype and PKtoPX are two programs Donald Knuth intended as
model DVI and PK file readers, and as containers for the
canonical documentation of the DVI and PK file formats. They
might be available as part of your TeX distribution, but are
also available on CTAN, in /tex-archive/systems/knuth/texware/dvitype.web
and /tex-archive/systems/knuth/pxl/pktopx.web.
The DVI Driver Standard, Level 0 is available on
CTAN, in directory /tex-archive/dviware/driv-standard. This
incorporates sections of the DVItype documentation. This
program claims to conform to this standard: if it doesn't,
please let me know.
Thanks for bug reports and other suggestions to Eitan
Gurari (heroic tester), Oliver Schurr and Oleg
Bartunov (oleg@sai.msu.su).
