+    The \pkgnoidx'{pcatcode} functionality would work best if it were built into the
+    \usecsn{latex2e} kernel, but it cannot be usefully added to the kernel now without
+    adversely affecting document compatibility across different systems. This package
+    therefore modifies one or two of the low-level package-loading functions defined
+    by the kernel. Theoretically speaking, the \pkgnoidx'{pcatcode} itself has to guard against the
+    kind of catcode problems that it is intended to circumvent. If you would like a
+    nice little \tex\unskip nician's exercise, try your hand, before looking at the code of the
+    \pkgnoidx'{pcatcode}, at the task that I set for myself: find the minimal set of catcode
+    assumptions that one has to make before attempting to establish normalcy, where normalcy is
+    defined as the state at the end of the \latex kernel, just before the last
+    \hx{\makeatother}. This is the state that may normally be expected at the
+    beginning of a \hx{\documentclass} file, if the \latex format file does not
+    have any extensions (\eg, \pkgm{babel}) compiled in.

+%   This is 'catoptions' package (Version 0.1, August 2010)               %
+%                                                                         %
+%   The catoptions package changes LaTeX package loading internals        %
+%   so that all subsequently loaded packages can rely on having           %
+%   normal catcodes in effect. The package also contains some useful      %
+%   macros unconnected with catcodes. In particular, it contains          %
+%   options processing facilities that have the familiar and simple       %
+%   syntax of LaTeX's legacy options parsing mechanism, but with          %
+%   improved robustness in terms of option value default, preservation    %
+%   of braces in option values, and parsing of expandable package         %
+%   and class option values.                                              %

+%   The catcode facilities of the package are an extension of the         %
+%   'pcatcode' package by Michael J. Downes and David M. Jones.           %
