+1 SCREENVIEW
+
+USAGE: SCREENVIEW input_file [first_page max_pages magnification]
+
+EXAMPLE: $ tex foo ! or latex foo
+ $ screenview foo.dvi
+ $ set term/width=132 ! depending on the text width
+ $ type foo.txt
+
+The SCREENVIEW command translates a given DVI file into a text file
+suitable for viewing on any sort of terminal. It can be useful for
+generating on-line documentation from a TeX or LaTeX source.
+To try and fit the output lines within 80 columns you will probably
+need to change the text width in the TeX or LaTeX source file.
+To do this in TeX simply include some commands near the top of your file:
+
+ \hoffset=0in % for a 1in left margin
+ \hsize=4.5in
+
+For LaTeX, a new style called "screen" can be used; simply add it after
+any other styles you use:
+
+ \documentstyle[uacs,screen]{article}
+
+The "screen" style sets up appropriate margins and text width, redefines
+all the type size commands to \normalsize and all the type style commands
+to \tt, then switches to \tt and uses \raggedright.
+
+The file created by SCREENVIEW can also be used to check line-breaks
+and page-breaks. Note that the horizontal and vertical positioning of
+text is only roughly approximated. In particular, the right margin
+of paragraphs will usually appear ragged. Also, characters from non-text
+fonts (such as math symbols) will appear incorrect.
+
+If you want to use the parameters after the file name then they must
+appear in the right order. For example, to select pages 5 and 6
+you would have to type "SCREENVIEW FOO 5 2".
+
+The magnification parameter is given as a percentage (default is 100)
+and controls the horizontal spacing of words. If the predominant type
+size is large, the magnification may need to be reduced, or else the
+words will be badly spread out.
