%   VERTICAL RULERS 2.3 Oct 1996 for Latex 2.09 or 2e, plain TeX, amsTeX
%            by  Zhuhan JIANG http://staff.scm.uws.edu.au/~zhuhan/
%                
%   LICENSE: LPPL v1 or later.
%
%   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
%

         This is a simple example, in which we have
         placed vertical rulers on the left for
         odd numbered pages and on the right for
         even numbered pages. \newpage

         This is the second page and is thus an even
         numbered page. Please see that the vertical
         ruler is now on the right, and is approximately
         of the same distance from the text margin as
         the vertical ruler on the first page from
         the left margin there. \newpage
\unsetvruler
         The following pages, in fact only this page, will
         not be appended with the vertical rulers.\newpage
\setvruler[][\rulercount]
         This page will be added with the vertical ruler again.
         Here the numbering marking of the vertical ruler picks
         up where it was left. Nevertheless, we may start with
         any new number. \newpage

         This is another page. Please see that both this and
         the previous pages have vruler on the left side.
