Contents and Notes
------------------

\makeescape, ..., \makecomment allow users to change category
codes a little more easily.

\savecat#1 and \restorecat#1 will save and restore the category
of a given character.  These are useful in cases where one doesn't
wish to localize the settings and therefore be required to globally
define or set things.

\SaveCS#1 and \RestoreCS#1 save and restore `meanings' of control
sequences.  Again this is useful in cases where one doesn't want to
localize or where global definitions clobber a control sequence which
is needed later with its `old' definition.

Abbreviations.  Just a listing with indications of expansion where
that may not be obvious.  For full definitions, see real code above.
