dviinfox.pl

Perl script which prints information about a DVI file. It supports not only the standard DVI format of TeX, but also the extended DVI format of pTeX containing vertical direction. It also accepts XDV format of XeTeX containing native font definitions.

This is a joint effort of Dag Langmyhr (Department of Informatics, University of Oslo) and Hironobu Yamashita (Japanese TeX Development Community).

Additional Notes

The perl script was originally named "dviinfo" by Dag Langmyhr, and renamed "dviinfox" in 2017, to be easily distinguished from another program written in C by Valentino Kyriakides (Dviinfo revision 1.3 1993/11/23 22:49:30). The C program seems to be derived from NeXTSTEP app in 1990s, and it has nothing to do with our perl script.
