+ * Revision 1.39 2006/09/08 09:49:23 fabiankeil
+ * Deliver documents in the user-manual directory
+ * with "Content-Type text/css" if their filename
+ * ends with ".css".
+ *
+ * Revision 1.38 2006/09/06 18:45:03 fabiankeil
+ * Incorporate modified version of Roland Rosenfeld's patch to
+ * optionally access the user-manual via Privoxy. Closes patch 679075.
+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.37 2006/07/18 14:48:45 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.35.2.7 2006/01/29 23:10:56 david__schmidt
+ * Multiple filter file support
+ *
+ * Revision 1.35.2.6 2005/07/04 03:13:43 david__schmidt
+ * Undo some damaging memory leak patches
+ *
+ * Revision 1.35.2.5 2005/05/07 21:50:55 david__schmidt
+ * A few memory leaks plugged (mostly on error paths)
+ *
+ * Revision 1.35.2.4 2005/04/04 02:21:24 david__schmidt
+ * Another instance of:
+ * Don't show "Edit" buttons #ifndef FEATURE_CGI_EDIT_ACTIONS
+ * Thanks to Magnus Holmgren for the patch
+ *
+ * Revision 1.35.2.3 2003/12/17 16:34:15 oes
+ * - Prevent line wrap beween "View/Edit" link buttons on status page
+ * - Some (mostly irrelevant) fixes for Out-of-mem-case handling
+ *
+ * Revision 1.35.2.2 2003/04/03 13:48:28 oes
+ * Don't show "Edit" buttons #ifndef FEATURE_CGI_EDIT_ACTIONS
+ *
+ * Revision 1.35.2.1 2002/07/04 15:02:38 oes
+ * Added ability to send redirects to send-banner CGI, so that it can completely mimic the image blocking action if called with type=auto
+ *
+ * Revision 1.35.2.1 2002/07/01 17:32:04 morcego
+ * Applying patch from Andreas as provided by Hal on the list.
+ * Message-ID: <20020701121218.V1606@feenix.burgiss.net>
+ *
+ * Revision 1.35 2002/05/12 21:44:44 jongfoster
+ * Adding amiga.[ch] revision information, if on an amiga.
+ *
+ * Revision 1.34 2002/04/30 12:06:12 oes
+ * Deleted unused code from default_cgi
+ *
* Revision 1.33 2002/04/30 11:14:52 oes
* Made csp the first parameter in *action_to_html
*
* type : Selects the type of banner between "trans", "logo",
* and "auto". Defaults to "logo" if absent or invalid.
* "auto" means to select as if we were image-blocking.
