+% Provides commands to change the page layout in the middle of a document,
+% and to robustly check for typesetting on odd or even pages.
+% Instructions for use are at the end of this file.
+%
+% This package is an extraction of code from the memoir class. It is
+% intended to eventually replace the chngpage package.

+% Usage:
+% ------
+%
+% \usepackage[strict]{changepage}
+%
+%%%%%%%%%%%%%%%
+% \checkoddpage
+%%%%%%%%%%%%%%%
+%
+% The \checkoddpage command can be used anywhere in the body of
+% a document to determine if TeX is typesetting on an odd or
+% even numbered page. If on an odd page then \ifoddpage is
+% set TRUE, otherwise (on an even page) \ifoddpage is set
+% FALSE.
+%
+% Strict page checking works by the \checkoddpage command generating
+% a label and then checking the \pageref for the label (actually, a special
+% version of \pageref is required and is used internally by \checkoddpage).
+% This mechanism requires at least two LaTeX passes to ensure that
+% the labels have settled (on the initial pass there will be no labels
+% in the *.aux file to be checked).
+%
+% The label identifier is composed of the command \cplabel
+% and an automatically generated number. \cplabel, initially
+% defined as `^_', can be changed in the preamble if it will cause
+% a clash with any author-defined labels. The default labels will
+% be of the form `^_N' where N is a positive integer.
+%
+% The package option `strict' turns on strict page checking --- the default
+% is not to use strict checking. Strict page checking can be turned on or
+% off at any time by the commands \strictpagecheck or \easypagecheck.
+% The easy page check just tests the page number to see if it is odd or even,
+% which does not always give the correct result because of TeX's asynchronous
+% output mechanism.
+%
+%%%%%%%%%%%%%
+% adjustwidth
+%%%%%%%%%%%%%
+% Within an adjustwidth environment the left and right margins can be
+% adjusted. The environment takes two required length arguments:
+%
+% \begin{adjustwidth}{leftmargin}{rightmargin}
+%
+% A positive length value will increase the relevant margin (shortening
+% the text lines) while a negative length value will decrease the margin
+% (lengthening text lines). An empty length argument means no change
+% to the margin. At the end of the environment the margins revert to
+% their original values.
+%
+% For example, to extend the text into the right margin:
+% \begin{adjustwidth}{}{-8em}
+%
+% The starred version, adjustwidth*, causes the values of the
+% margins to switch between odd and even pages.
+%
+% If the document is being set twosided it might be advantageous
+% to have any wider text extending into the outside margin. This
+% could be done via the optional argument, as:
+% \begin{adjustwidth*}{}{-8em}
+%
+% To have the adjusted text horizontally centered with respect to
+% any surrounding text, the margins should be adjusted equally:
+% \begin{adjustwidth}{-4em}{-4em}
+%
+% For interest, \begin{quotation} is pretty much equivalent
+% to \begin{adjustwidth}{2.5em}{2.5em}
+%
+% The environment may also be used inside a float if the contents are
+% a bit too wide for the text block, but can still fit within the physical
+% page:
+% \begin{figure}
+% \begin{adjustwidth}{-2em}{-2em}
+% \includegraphics{wide}
+% \caption{Wide figure}
+% \end{adjustwidth}
+% \end{figure}
+%
+% Sometimes, because of the asynchronous nature of the TeX output
+% routine, the margin switching may be incorrect (like \marginpar sometimes)
+% near the top of a page. This can be corrected by using the package
+% option `strict' (i.e., \usepackage[strict]{chngpage}), which causes
+% adjustwidth to use the \checkoddpage command (see below).
+%
+% A disadvantage of the strict option is that the package generates
+% a new label for each adjustwidth environment, and TeX may run out
+% of space if there are an excessive number of labels in the document.
+%
+% Whether or not the strict option is used, `strict adjustwidths'
+% can be turned on by putting the command \strictpagecheck before
+% the environment, and turned off by using \easypagecheck.
+%
+% NOTE: In a twocolumn document, the adjustwidth environment
+% treats both columns equally. For example, if the width is meant
+% to be wider at the outer margin, then on odd pages the extra width
+% will be at the right of any column, and on even pages the extra
+% will be at the left of any column. You can get interesting effects
+% by careful hand tuning on two column pages.
+%
+%%%%%%%%%%%%%
+% \changetext
+%%%%%%%%%%%%%
+% The \changetext command is for changing the size and horizontal position
+% of the text block on a page. The command takes 5 arguments, each of which
+% is a length or is empty. i.e.,
+%
+% \changetext{textheight}{textwidth}{evensidemargin}{oddsidemargin}{columnsep}
+%
+% The given lengths are added to the corresponding current lengths and
+% the remainder of the current page is typeset using the changed text block
+% layout. The new layout remains in effect until another \change... command
+% is issued.
+%
+%%%%%%%%%%%%%
+% \changepage
+%%%%%%%%%%%%%
+% The \changepage command is for changing the general layout of
+% a page. The command takes 9 arguments, each of which is a length or is empty.
+% The first 5 arguments are the same as for \changetext and have the same effect.
+% The last four arguments are:
+%
+% \changepage{5 args}{topmargin}{headheight}{headsep}{footskip}
+%
+% These lengths are added to the corresponding current lengths and
+% thus modify the vertical positions of the elements of the page. The
+% remainder of the current page is typeset using the changed text block
+% and page layout. The new layout remains in effect until another
+% \change... command is issued.
+%
+% NOTE 1: Not supplying a value for a length argument is equivalent
+% to giving it a zero length value.
+%
+% NOTE 2: For any given page, everything is constant except for the textwidth
+% and columnsep (for example, what is the meaning of two
+% topmargins on a single column page?).
+% It is therefore best to change anything else at the
+% start of a new page. Further, any changes only apply to whole
+% paragraphs. If you want an odd shaped paragraph use either
+% the hanging package or the TeX \parshape command.
+%
+% For example, to change from single column pages to double column
+% pages where the text block is both shorter and wider, then to revert
+% back to the initial layout:
+% ... single column normal page
+% \newpage % or \clearpage
+% \changetext{-5\baselineskip}{10em}{-5em}{-5em}{}
+% \twocolumn
+% ... two column pages
+% \clearpage
+% \changetext{5\baselineskip}{-10em}{5em}{5em}{}
+% \onecolumn
+% ... normal pages
+%
+% Note the adjustments to the margins which will keep the vertical centerline
+% of the textblock at the same position on the page.
+%
+% As another example, to increase the width of a single paragraph:
+%
+% \changetext{0pt}{5em}{}{}{}%
+% Start of wider paragraph text ...
+% ... end of paragraph.
+%
+% \changetext{0pt}{-5em}{}{}{}
+% Start of a normal paragraph ...
+%
+% Under some circumstances you can include a \change... command as part of
+% the argument to \afterpage (from the afterpage package) and it may work.
+% Similarly it may work in a heading style used for \thispagestyle to change
+% a single page.
