+ % Making those `Label(s) have changed\dots' messages more explicit
+%
+% The \LaTeX{} kernel produces the messages when something, while the
+% |.aux| file is being scanned (after the \cs{AtEndDocument} tokens
+% have been executed), sets the \cs{if@tempswa} switch with the
+% command \cs{@tempswatrue}.
+%
+% (This fact can be used by packages, such as my |footmisc.sty|, to
+% piggy-back on the message; but it's nice in that circumstance and
+% others to be sure where the message is coming from.)
+%
+% This is a jiffy patch to the kernel so that it produces a
+% (\cs{typeout}) message for each label \emph{it} thinks has changed.
+%
+% Usage: Incorporate this code into a package or class file,       or
+%        \input this file from a package or class file,            or
+%        \makeatletter \input{checklab} \makeatother in your document
+%                                                    preamble
+%
+% This software jiffy is placed in the public domain.  Do with it as
+% you wish, though I have to say I would prefer you not to claim it
+% as your own (otoh, it's the product of a twisted mind, so probably
+% not an attractive thing to claim).
