%
% This file is beer-ware. If you use it and like it, then you
% should buy me a beer if you ever meet me. :-)
%
%
% INTRO
%
% This is a fairly simple file, so I am not going to bother with a
% .dtx file. Here is the whole documentation, right here. :-) No
% \docstrip{} hastle or anything...
%
%
% WHY THIS PACKAGE?
%
% I think the default printable area used by \LaTeX{}, frankly,
% sucks. When I turn in three problem assignments for a math class
% and it takes up eight pages, there is just too much blank space.
% So, I hacked the relevant parts out of |classes.dtx| which deal
% with setting printable area and balancing margins and fiddled with
% some of the default values. Not only that, but it is easily
% customisable.
%
%
% HOW TO USE THIS PACKAGE
%
% There are two basic ways to use this package. Essentially, after
% including the package, the macro |\resize| is available to the
% user. After altering any of the relevant page information, one
% can invoke |\resize| to recalculate page margins. |\resize|
% should be called after changes to the following:
%
% \textheight \headheight \footskip
% \textwidth \headsep
%
% and optionally after changing |\topskip|. These are the
% dimensions on which the \LaTeX{} algorithms below depend.
%
% This only half solves the problem, though. Having to change the
% height and width in every document is also not a particularly
% ducky solution, so there is also a package option, namely |auto|.
% In commented sections below, you will see where I have altered
% some of the default values that \LaTeX{} uses for page layout
% calculations. Invoking the package with the |auto| option will
% automatically do a resize with these defaults. Of course, the
% |\resize| command will still be available if further modifications
% are desired. You should feel perfectly free to change these
% defaults to something that will be more appropriate for you.
% As the major advantage of \LaTeX's default, \emph{wide} margins is
% the availability of |\marginpar| space, for draft annotations, I
% also consider the revised margins of this package to be applicable
% to final output. Therefore the option |final| will be grabbed and
% interpreted to mean the same thing as |auto|.
%
%
% BUGS
%
% Well, I wouldn't call this a bug, but I haven't accounted for the
% slight differences in these calculations specific to the |book|
% class's options for size switching. This package was written in
% about twenty minutes, and I couldn't think of a way off the type
% of my head to test for the invoked class. If there is one (and
% I'm fairly sure there is), please let me know.
%
%
% COMMENTS?
%
% If you have any, send them to me at one of the e-mail addresses
% above. I hope this will be useful to somebody, somewhere.
