Each single <strong>package</strong> support can be switched on or off by using <strong>the</strong> appropriate option.<br />

By <strong>de</strong>fault all of <strong>the</strong>m are enabled.<br />

611 \newcommand*\<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>[1]{%<br />

612 \<strong>caption</strong>@setbool{pkt@#1}{1}%<br />

613 \DeclareCaptionOption*{#1}{\<strong>caption</strong>@setbool{pkt@#1}{##1}}}<br />

614 \AtEndOfPackage{\let\<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>\@un<strong>de</strong>fined}<br />

\<strong>caption</strong>@if<strong>package</strong> \<strong>caption</strong>@if<strong>package</strong>{〈<strong>package</strong> name〉}{〈<strong>package</strong> macro〉}{〈co<strong>de</strong>〉}<br />

If a certain <strong>package</strong> support is requested <strong>the</strong> appropriate co<strong>de</strong> will be used. ‘Requested’<br />

means that <strong>the</strong> option belonging to it is set to true and <strong>the</strong> macro called 〈<strong>package</strong> macro〉<br />

is <strong>de</strong>fined. (If 〈<strong>package</strong> macro〉 is not yet <strong>de</strong>fined we use \AtBeginDocument here,<br />

so <strong>the</strong> <strong>package</strong> could be loa<strong>de</strong>d after this <strong>package</strong>, too.)<br />

615 \newcommand\<strong>caption</strong>@if<strong>package</strong>[3]{%<br />

616 \e<strong>de</strong>f\<strong>caption</strong>@tempa{%<br />

617 \<strong>caption</strong>@ifbool{pkt@#1}%<br />

618 {\@ifun<strong>de</strong>fined{#2}{AtBeginDocument}{firstofone}}%<br />

619 {gobble}}%<br />

620 \<strong>caption</strong>@Info{#1=\<strong>caption</strong>@ifbool{pkt@#1}{1}{0} %<br />

621 (\@ifun<strong>de</strong>fined{#2}{not }{}loa<strong>de</strong>d->\<strong>caption</strong>@tempa)}%<br />

622 \<strong>caption</strong>@ifbool{pkt@#1}{%<br />

623 \@ifun<strong>de</strong>fined{#2}%<br />

624 {\let\<strong>caption</strong>@tempa\AtBeginDocument}%<br />

625 {\let\<strong>caption</strong>@tempa\@firstofone}%<br />

626 }{%<br />

627 \let\<strong>caption</strong>@tempa\@gobble<br />

628 }%<br />

629 \<strong>caption</strong>@tempa{\@ifun<strong>de</strong>fined{#2}{}{#3}}%<br />

630 \<strong>caption</strong>@un<strong>de</strong>fbool{pkt@#1}}<br />

631 \AtEndOfPackage{\let\<strong>caption</strong>@if<strong>package</strong>\@un<strong>de</strong>fined}<br />

You can also switch <strong>the</strong> <strong>caption</strong> support off using <strong>the</strong> <strong>package</strong> option <strong>caption</strong>=false.<br />

This may look strange, but <strong>the</strong>re are certain circumstances where this could be useful.<br />

Such a situation might be <strong>the</strong> usage of <strong>the</strong> subfig <strong>package</strong> <strong>with</strong>out disturbing <strong>the</strong> main<br />

<strong>caption</strong> co<strong>de</strong> of <strong>the</strong> document class.<br />

Note: This mechanism is obsolete now, it has been supersee<strong>de</strong>d by <strong>the</strong> subfig <strong>package</strong><br />

option <strong>caption</strong>=false which causes that only <strong>the</strong> <strong>caption</strong> kernel <strong>caption</strong>3 is loa<strong>de</strong>d.<br />

632 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{<strong>caption</strong>}<br />

These are <strong>the</strong> <strong>package</strong>s we support:<br />

633 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{float}<br />

634 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{floatrow}<br />

635 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{hyperref}<br />

636 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{hypcap}<br />

637 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{listings}<br />

638 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{longtable}<br />

639 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{picins}<br />

640 \<strong>caption</strong>@<strong>de</strong>clare<strong>package</strong>{rotating}<br />
