Added required file, remove use of ncs style. (Non standard, and doesn't

work anyway, currently.)

+% Change bar document-style option for LaTeX.
+%
+% Copyright (C) 1990 by David B. Johnson.
+
+% These macros draw a solid bar down the right margin of the output,
+% covering a range of the input file that has been declared to be changed.
+%
+% The beginning and end of a change bar in the text are marked with
+% \chgbarbegin and \chgbarend, respectively.  For example,
+%
+%     Here is some sample text \chgbarbegin that was
+%     changed\chgbarend{} and some that wasn't changed.
+%
+% The change bar is drawn continuously between the line of output
+% containing the \chgbarbegin and the line of output containing the
+% \chgbarend.  These lines can end up on separate pages, and the
+% division at page boundaries is handled automatically.
+
+% Two dimensions control the size and placement of the change bars:
+%     \chgbarwidth      The width of a change bar
+%     \chgbarsep        The distance between the text and the change bar
+
+% Warning: it does not appear to be possible to do this completely
+% correctly, due to the time at which the verticle glue on a page is
+% finally set, and the way that page breaks are decided.  With
+% \raggedbottom, this normally works fine.  It hasn't been tested with
+% \flushbottom, but will probably behave worse.  In strange rare 
+% situations, a change bar might be drawn from the first line of a page
+% up off the top of a page; this can usually be fixed by slightly moving
+% the \chngbarend around, or by breaking a single change bar range
+% into two ranges.
