+%   VERTICAL RULERS 2.3 Oct 1996 for Latex 2.09 or 2e, plain TeX, amsTeX
+%            by  Zhuhan JIANG, University of New England, Australia NSW 2351.
+%                Email: zhuhan@neumann.une.edu.au
+%
+%   PURPOSE: Make a vertical ruler, numbering consecutively so that
+%            any part of an article can be pinpointed immediately.
+%            Move vruler freely up and down, left and right.
+%         
+%            There are no packages to my knowledge that number lines
+%            one by one without missing certain lines, particularly
+%            when there are many maths equations in the text. So vruler
+%            is a good alternative for people writing text of versatile
+%            format or lots of maths formulas.
+%   COMMANDS:
+%     \setvruler[<SCALE>][<INITIAL_COUNT>][<STEP>][<DIGITS>][<MODE>]%
+%              [<ODD_HSHIFT]>][<EVEN_HSHIFT>][<VSHIFT>][<HEIGHT>]
+%         <general LaTeX material-01>
+%     \unsetvruler  % optional
+%         <general LaTeX material-02>
+%
+%         <SCALE>   distance between two consecutive vruler markings
+%         <INITIAL_COUNT> first marking reading
+%         <STEP>    is the line count increment
+%         <DIGITS>  number of digits required for ruler markings
+%         <MODE> =0 if each page has same vruler marking, =1 if otherwise
+%         <ODD_HSHIFT>  horizontal shift for odd pages
+%                       from the default value for the vruler
+%         <EVEN_HSHIFT> horizontal shift for even pages
+%                       from the default value for the vruler
+%         <VSHIFT>  vertical shift from default value for vruler
+%         <HEIGHT>  height of vertical ruler
+%
+%     \vrulercount   - next mark reading on the vertical ruler
+%
+%     \setdefault{cmdname}{n}{default_1}{..}{default_n} (re)set macro
+%         \cmdname[#1][..][#n] to take default_1 to default_n respectively,
+%         so that \cmdname[][xy] is same as \cmdname[default_1][xy][default..].
+%         You don't need to use \setdefault unless you would like to change
+%         the default setting for macros in vruler.sty or elsewhere.
+%
+%   DEFAULTS:
+%     The parameters of \setvruler admit defaults.
+%     Hence e.g. \setvruler alone is same as
+%         \setvruler[10pt][1][1][4][1][0pt][0pt][0pt][\textheight]
+%     and e.g. \setvruler[][20] is same as \setvruler[10pt][20]
+%
+%   NOTES:
+%     1.  If you are using multicol.sty, then you might want to move
+%         the vruler into the center to separate the columns.
+%
+%     2.  If you use \topskip other than the default value, then
+%         you will have to alter <VSHIFT> and <HEIGHT> parameters
+%         in \setvruler accordingly (which is simple). 
+%
+%     3.  It is best to choose baselineskip as <SCALE> so that line
+%         synchronisation is often optimal. Use e.g. 5+ to denote
+%         the line immediately after marking number 5 if necessary.
+%
+%     4.  In twosided book style in LaTeX2e, the initial numbering
+%         of title page  via  \begin{titlepage} is actually onepage
+%         away. To overcome this, either do not include title page in
+%         the vruler environment, or set initial number #2
+%         to a number (a page ahead) so that the resulting
+%         initial number is what one needs.
+%           
+%     5.  Version 1.0 of VRULER.STY for LaTeX is released in
+%         July 1993.
+%
+%   EXAMPLE:   see end of this file.
+%         You may run the example by simply removing the line 
+%         containing \endinput
