.TH DVITYPE 1 "7 Jan 92"
.SH NAME
dvitype - translate a dvi file for humans
.SH SYNOPSIS
.B dvitype
dvi_file_name
.SH DESCRIPTION
The
.I dvitype
program translates a DVI (DeVice Independent) file output by, for example,
.BR tex (1)
or
.BR gftodvi (1),
to a file that humans can read. It also serves as a DVI file-validating
program (i.e., if
.I dvitype
can read it, it's correct) and as an example of a DVI-reading
program for future device drivers.
.PP
The output file can include all commands, just the important
ones, or none at all (in which case only errors are reported).
A subinterval of pages may be selected for transliteration; the
magnification and resolution of the ``output device'' may be
changed; and so on. All options are specified with an on-line dialog.
.PP
The
.I dvi_file_name
on the command line must be complete. The
.I .dvi
extension is not supplied if omitted. The output goes to
.IR stdout .
.SH ENVIRONMENT
The environment variable TEXFONTS is used to search for the TFM files
used in the DVI file.  See
.BR tex (1)
for the details of the searching.
If TEXFONTS is not set, it uses the system default: 
.BR /usr/local/lib/tex/fonts/tfm:. .
