+ *    Revision 1.75  2006/09/07 11:56:39  fabiankeil
+ *    Mark cgi_send_user_manual as harmless,
+ *    to fix the access denied problem Hal spotted.
+ *    The manual has no secret content, therefore we
+ *    don't have to care about "secure" referrers.
+ *
+ *    Revision 1.74  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.

  *    Incorporate Fabian Keil's patch work:
