*
* Org-mode >= 6.12a
*
* Org-mode > 6.23 (commit a68eb4b1e64cbe6e495fdd2c1eaf8ae597bf8602):
* You'll need at least org-info.js v.0.1.0.1
*
* Usage:
*
* Include this scipt into the Header of your HTML-exported org files by
* customizing the variable org-export-html-style (TODO: add file local export
* Options here).
* You will also need this here somewhere in the HTML-page:
*
* <script type="text/javascript" language="JavaScript" src="org-info.js"></script>
* <script type="text/javascript" language="JavaScript">
* <![CDATA[ // comment around this one
* org_html_manager.set("LOCAL_TOC", "1");
* org_html_manager.set("VIEW", "info");
* org_html_manager.set("VIEW_BUTTONS", "true");
* org_html_manager.set("LINK_UP", "http://full/path/to/index/of/this/directory.html");
* org_html_manager.set("LINK_HOME", "http://full/path/to/homepage.html");
* org_html_manager.set("MOUSE_HINT", "underline"); // or a color like '#eeeeee'
* org_html_manager.setup ();
* ]]> // comment around this one
* </script>
*
*
* The script is now roughly devided in sections by form-feeds. Editors can
* move section wise using the common emacs commands for this purpos ('C-x ]'
* and 'C-x ]').
*
* The sections are:
* 1. This comment block.
* 2. Everything around =OrgNodes=.
* 3. =org_html_manager= constructor and setup.
* 4. =org_html_manager= folding and view related stuff.
* 5. =org_html_manager= history related methods.
* 6. =org_html_manager= minibuffer handling.
* 7. =org_html_manager= user input.
* 8. =org_html_manager= search functonality.
* 9. =org_html_manager= misc.
* 10. Global functions.
