<html><head><meta name="color-scheme" content="light dark"></head><body><pre style="word-wrap: break-word; white-space: pre-wrap;">% This package is covered by the LaTeX project public license 
% (see \url{http://www.latex-project.org/lppl.txt}). 
% Please report bugs to the author (Michael Palmer, mpalmer@uwaterloo.ca) 

% modifications since 1.1:
% - added second optional argument to \note (tikz code)
% - expunged package ifthen, since we require etoolbox anyway
% - added package name to default pdfcreator string
% - added 'important' option for applying different note formatting
% - added 'staggered' option to prevent overlapping placement of notes
% - added 'scaletopage' option to pick a page other than the first one
%   in case that one has an atypical size, as sometimes happens. 
% - added \pagegrid user macro to draw a grid of helplines over top
%   the included source page.

% In the docs, we should tell the users that the page environment is, in fact,
% a tikzpicture - so they can use nodes etc inside it. Maybe we should 
% specify a relative unit for the x axis also? yes, we do now. we also shift
% the scope, so that the origin is always at the bottom left of the source page. 
% we also need to add to the docs that the leftnotes env can stay - you don't 
% need to remove it when you set twocolumn to false.
