+This package is an extension of Peter Wilson's 'changepage' package. 
+It can be used to change text and page layout parameters locally 
+(per page) or globally (for the whole document). The original 
+layout parameters can be recovered at any time during runtime.

+\begin{comment}
+  'switchadjust' is a boolean for switching left and right margins on
+  odd and even pages.
+
+  'strictcheck' is a boolean for enforcing strict page number check
+  (the idea is from the 'changepage' package). For a large document,
+  'strictcheck' will generate a corresponding large number of
+  labels. This is not expected to be a problem with modern implementations
+  of TeX/LaTeX.

+\begin{comment}
+  In addition to \changetextlayout, there is also \changepagelayout.
+  Both \changetextlayout and \changepagelayout replace (in the total sense)
+  the prevailing text/page layout parameters by the values submitted by
+  the user. All the page layout parameters (including \marginparwidth)
+  can be changed/replaced by simply submitting their new values.
+\end{comment}

+\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.
+
+  The original and final layout parameters are written into the log
+  file (and displayed on the screen) by issuing 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.

+\begin{comment}
+  In addition to \adjusttextlayout, there is also \adjustpagelayout.
+  Both \adjusttextlayout and \adjustpagelayout adjust (by adding or
+  subtracting) the prevailing text/page layout parameters by the
+  values given by the user. All the text and page layout parameters
+  can be adjusted.
