.SH NAME
dvitype, odvitype \- translate a dvi file for humans
.SH SYNOPSIS
.B dvitype
.IR dvi_name [ \fB.dvi\fP ]
.\"=====================================================================
.SH DESCRIPTION
This manual page is not meant to be exhaustive.  The complete
documentation for this version of \*(TX can be found in the info file
or manual
.IR "Web2C: A TeX implementation" .
.PP
The
.B 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
.B 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
.B .dvi
extension is supplied if omitted from 
.IR dvi_name .
The output goes to
.IR stdout .
