-% TITLEREF.STY ver 3.1 2001-04-05 Donald Arseneau <asnd@triumf.ca>
-% This is free unsupported software, released to the public domain.
-%
-% This package provides a "\titleref" command to cross-reference the titles
-% of sections. The "\label" command is changed to remember the title for
-% such a reference. Use "\titleref" just like "\ref" and "\pageref".
-%
-% Titles for numbered sectioning units and for floats with captions are
-% the same as the respective TOC, LOF, or LOT entry (even when no TOC is
-% printed). When a short title is provided ("\section[short]{long}")
-% it will be used for the "\titleref". This is especially useful for
-% figure captions. Unnumbered sections take their title reference from
-% the printed title. Beware! This turns the title into a moving argument
-% when it normally is not, and will cause weird errors if there are
-% `fragile' commands present.
-%
-% Enumerated lists do not have titles and simply inherit the title of
-% their section.
-%
-% The format of the title reference is controlled by the command
-% "\theTitleReference", which can be redefined with "\renewcommand".
-% It takes two parameters: the number and the title. The number is
-% just the regular "\ref" and it is WRONG in unnumbered sections.
-% Beware! The default definition is the unadorned title. You could
-% do, for example, "\renewcommand{\theTitleReference}[2]{#1\ \emph{#2}}".
-%
-% The title of the current section is also available without "\label":
-% Use the command "\currenttitle" to generate a "\titleref" to the current
-% section. If you have redefined "\theTitleReference" to print the number
-% with the title, be aware that the two may not correspond: In a numbered
-% list the number will show the current item but the title will show the
-% current section, but in an unnumbered section the number will show
-% some previous section number.
-%
-% Options: [usetoc] and [nostar]
-%
-% In the default operation, the titles are recorded by a command inserted
-% into the various sectioning commands ("\@sect", "\@ssect", "\@chapter",
-% "\@schapter", "\@part", "\@spart", and "\@caption"). If this creates
-% conflicts with some other package, you can use an entirely different
-% method by specifying "\usepackage[usetoc]{titleref}". As the name
-% implies, this option records the titles from the table-of-contents
-% entry without redefining the sectioning commands. (This is the method
-% used in older versions.)
-%
-% Since there are no TOC entries for the `star' versions of sectioning
-% commands, they are still redefined. The additional option "[nostar]"
-% ("\usepackage[usetoc,nostar]{titlerrf}") prevents the redefinitions,
-% but then "\section*" will not generate a title reference. If you try
-% to refer to the title of an unnumbered section while "[nostar]" is in
-% effect, you will get the title of the previous section.
-%
-% Under the "[usetoc]" option, the current title will always be overridden
-% by an "\addcontentsline" command before the "\label", even for starred
-% section commands under the "[nostar]" option.
-%
-% The big problem with the "[usetoc]" method is that "\titleref" will
-% not refer to a "\label" which was given in the title or caption itself;
-% the label must be placed after the sectioning command or the caption.
-% If you make a title-reference to a label given in a title, you will get
-% a warning message.
