\begin{comment}
Make text width wider into right margin by 1.5cm on odd pages.
'switchadjust' is a boolean for switching left and right margins on
odd and even pages. This is useful for twoside printing, where
the user may want the text extended only into outer margins:
\end{comment}
\adjusttextwidth{switchadjust=true,leftmargin=-0cm,rightmargin=-1.5cm,
textcolor=xmagenta20,content=\csuse{temp3}}
\newpage
\lipsum[1-1]
\begin{comment}
Make text width wider into right margin by 1.5cm, but
'switchadjust=true' means that it is actually the left margin
that is made wider on even pages. If the value of 'switchadjust'
is 'true', you can simply enter 'switchadjust' without value:
\end{comment}
\adjusttextwidth{switchadjust,leftmargin=-0cm,rightmargin=-1.5cm,
textcolor=red,content=\csuse{temp4}}
\begin{comment}
'strictcheck' is a boolean for enforcing strict page number check
(the idea is from the 'changepage' package). See the
\usepackage{changelayout} statement above.
Strict page checking is a safeguard against unlikely changes
to the kernel page counter by another macro or package. For a
large document, 'strictcheck' will generate a correspondingly
large number of labels. This is not expected to be a problem
with modern implementations of TeX/LaTeX; so I decided to
retain it.
\end{comment}
\newpage
\begin{comment}
The layout of individual pages can be changed by using
\changepagelayout or \changetextlayout (they are synonymous).
Both \changetextlayout and \changepagelayout replace (in the
total sense) the prevailing text/page layout parameters by the
values submitted by the user through these macros. All the page
layout parameters (including \marginpar parameters) can be
changed/replaced by simply submitting (via these macros)
the new parameter values.

\resetdefault%
\begin{comment}
\resetdefault is a command for resetting page/text layout parameters
to the default values. The default parameters are saved at each run.
If the 'geometry' package is loaded, the default parameters will be
those determined by 'geometry'. \resetdefault is very handy for
recovering from page/text layout changes.
The original and final layout parameters are written into the log
file (and displayed on the screen) if the user issues the booleans
'logdefault' and 'logfinal' (respectively) as options to the
package (preferably at \usepackage). These may be useful when deciding
on the changes or adjustments to be effected.
\end{comment}
\begin{comment}
In addition to \changepagelayout and \changetextlayout, there are
also \adjustpagelayout and \adjusttextlayout (again these
are synonymous).
Both \adjustpagelayout and \adjusttextlayout adjust (by adding to or
subtracting from) the prevailing text/page layout parameters the
values given by the user. All the text and page layout parameters
can be 'adjusted' by using these macros.
