\ProvidesPackage{fix-unnumbered-sections}

% This package is available at http://tex.stackexchange.com/q/33696/
% It patches the standard classes so that they treat unnumbered and numbered sections equally! (At least, I've tested it with the article class.)
% As a result, even the unnumbered sections gets entries in the TOC and, when hyperref is loaded, they also get bookmarks as per the default hyperref setting for bookmarks.
% Unnumbered sections can also have short titles for TOC and bookmark purposes, just like numbered sections.
%
% It works by pretending the unnumbered sections are deeper than \c@secnumdepth (in fact, just by assuming that they are 1000 (\@m) levels deep).
% I believe there are no side effects to this...

% We just pretend that \@ssect, which LaTeX uses to treat unnumbered [sub*]sections differently to (maybe) numbered ones (if they are no deeper than \c@secnumdepth levels), doesn't exist.
% Instead, we always use \@sect, which LaTeX uses for numbered sections, and sections which would otherwise be numbered if they weren't deeper than \c@secnumdepth levels.
