You can use the 'viewscribe' previewer to look at Scribe PostScript documents
that don't contain graphics.  To those of you who used viewdoc in the past, it
should look very familiar.  To use it, type:

	viewscribe filename.PS &

(where 'filename.PS' is the name of the file you want to view)

After you type the 'viewscribe' command, move the mouse to the upper left hand
corner of your screen, and then press the left mouse button.  Inside the
document previewer, you can go forward a page, back a page, or exit.  You do
this either by clicking a mouse button on the appropriate box at the upper
left of the window, or by pressing:

	Left Button:    next page
	Middle Button:  previous page
		(that's both buttons simultaneously on a two-button mouse)
	Right Button:   exit

You can go to any page by typing the number of the page and hitting return.
Viewscribe counts pages from the beginning of the document including title
page and tables of contents.  This means that the page with the number '2' at
the bottom might actually be page 4 of the document.  You would have to type
'4<return>' to go to this page.

Because PostScript fonts are different than the X fonts used to display the
text on the screen of a workstation, viewscribe needs to be told what X fonts
to use to print the Postscript fonts on the screen.  While it has a built-in
table of some translations, you may encounter the error

	X Toolkit Warning: couldn't find /fontname size.  Using default.

if it encounters a font that isn't in it's translation table.  If this
happens, you can add to the font translation table with a .postpsfonts file in
your home directory.  There is a sample ..postpsfonts file available that
defines many of the fonts- to get a copy of it into your home directory, type:

	attach consult
	cp /mit/consult/lib/viewscribe/postpsfonts ~/.postpsfonts
