% This file is inserted into any PostScript generated by elvis.  It defines
% the following symbols:
%     ElvisN         push a 12-point normal font
%     ElvisB         push a 12-point bold font
%     ElvisI         push a 12-point italic font
%     ElvisPage      translate & scale a page to fit the paper
%     ElvisLeftPage  translate, rotate & scale to fit left half of paper
%     ElvisRightPage translate, rotate & scale to fit right half of paper
%     ElvisLeftEdge  CONSTANT offset to left edge of printable area
%     ElvisTopEdge   CONSTANT offset to right edge of printable area
%     ElvisWidth     CONSTANT width of printable area
%     ElvisHeight    CONSTANT height of printable area
%
% In addition, elvis itself inserts some header information before this file,
% in each PostScript output.  This includes the standard comments at the top
% of the job, and also defines the following from elvis' options...
%     ElvisPaper     CONSTANT name of the page size, such as (letter) or (a4)
%     ElvisLines     CONSTANT lines per logical page
%     ElvisColumns   CONSTANT columns per logical line
%     ElvisBar 	     CONSTANT BOOL bar separating pages in two-up format
%     ElvisFrame     CONSTANT BOOL frame around each page in two-up format
%     ElvisPunch     CONSTANT BOOL increase left margin to leave room for a 3-hole punch
%     ElvisClip      CONSTANT BOOL increase top margin for use with a clipboard

% Define the printing offsets.  These indicate where the *PRINTABLE* portion
% of each page starts.  This is likely to vary from one printer to another.
% The unit of measurement is a Point, approximately 1/72 of an inch.
