+catdvi can be used to transform TeX DVI files into text, losing
+formatting its main aim on SBo is to be used by recoll, when it cannot
+extract text from pdf files by other means.
+
+
+catdvi is a program that translates TeX Device Independent (DVI) files
+into readable plain text. The program is under development. It
+produces satisfactory results in many cases, but still has some issues
+with complicated input.
+
+Goals Actually, "translate to plain text" can mean several different
+things, depending on the intended use:
+
+Output formatted text that resembles the layout of the DVI file as
+closely as possible, suitable for e.g. preview on a character cell
+terminal or printing on a teletype style printer. Output unformatted
+text in "read order". (Rather than "print order", which makes quite a
+difference with e.g. multi-column page layouts). Useful for searching,
+indexing and other kinds of postprocessing, and maybe also for export
+to different text processors. Output (not completely plain) text in
+read order with the formatting distilled into some kind of markup so
+that paragraph breaks, subscripts, superscripts, etc. can still be
+recognized. This functionality is essentially a (La-)TeX decompiler,
+useful for recovery of lost or otherwise unavailable .tex files.
+catdvi's principal target is to create human-readable text files from
+DVI input, and hence the first kind of translation.
+
+The second kind is supported as well because one of the developers
+needed it and it could be obtained as an easy by-product (based on the
+mostly true assumption that read order = order in the source file =
+order in the DVI file).
+
+The third kind of translation is the most difficult one to achieve
+since a DVI file does not contain logical markup information. The
+structure of the text has to be guessed from heuristic principles and
+an analysis of certain characteristics of TeX's output. No attempt in
+this direction has been made so far. But knowledge of some aspects of
+text structure would also help to improve the quality of layout in
+case 1. If it turns out these can reliably be guessed, an option to
+show them as markup will probably follow. This feature has low
+priority at the moment, especially since nobody has expressed a need
+for it.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.
