I hope someone unifies fonts for all these applications some days and
standardizes thier structure. I have at least seven different font sets
on my system now. None of them compatible with any of the others. All
of them sucking up megabytes.
Xdvi's particular problem is with TeX which apparently doesn't have it's
fonts in the same directory structure from installation to installation.
We're using Arbor TeX on our Suns which is pretty good all in all, but
you really have to pamper xdvi to get it to find the fonts. I'll include
the little diff to path_open we're using, but I can't recommend it in
general.
Xdvi is also full of non-robust code. I'm constantly amazed that it
doesn't core dump with segementation faults.

X.I dvi_file
X.SH DESCRIPTION
X.I Xdvi
Xdisplays the DVI output file
X.I dvi_file
Xin an X window. The options do something that the author felt was self
Xevident. (No manual page was included in the source directory.) Good
Xluck.
X.SH ENVIRONMENT
XThe environment variable
X.B %%FONTPATH%%
Xis used to determine where
X.I TeX
Xpacked pixel fonts are to be searched for. I consists of multiple
Xdirectory names separated by colons (`:'). The default value of
X.B %%FONTPATH%%
Xis
X.BR %%DEFAULT_FONT_PATH%% .
X.I Xdvi
Xwill search for fonts in each of the directories listed and in
Xsubdirectories with the name of the font being searched for sans its
Xdotted extension (some systems store fonts in directories by family and
Xthen each size/scale within that directory). Thus for example, the font
Xcmcsc10.329pk would be searched for as cmcsc10.329pk and cmcsc/cmcsc10.329pk
Xin each of the directories listed in
X.IR %%FONTPATH%% .
X.PP
X If that search fails,
X.I xdvi
Xwill search through the directories in
X.B %%FONTPATH%%
Xagain searching for the best match to the font specified. (It doesn't
Xbother searching through subdirectories on this scan.) It looks for a font
Xin the same family, whose point size is closest first, and whose
Xmagnitude is closest second.
X.SH BUGS
XThis manual page is a token effort only. It would really be nice to get
Xone that actually gave one something other than a usage statement.
X.PP
XThe font search algorithm is a crock. In fact, the entire program is a
Xcrock. You don't want to look at the source, believe me! But, in the
Xabsence of anything better, this will do ...
