  *    $Log: cgisimple.c,v $
+ *    Revision 1.40  2006/09/09 13:05:33  fabiankeil
+ *    Modified cgi_send_user_manual to serve binary
+ *    content without destroying it first. Should also be
+ *    faster now. Added ".jpg" check for Content-Type guessing.
+ *
+ *    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
