  * Revisions   :
  *    $Log: jcc.c,v $
+ *    Revision 1.24  2001/07/13 14:00:40  oes
+ *     - Generic content modification scheme:
+ *       Each feature has its own applicability flag that is set
+ *       from csp->action->flags.
+ *       Replaced the "filtering" int flag , by a function pointer
+ *       "content_filter" to the function that will do the content
+ *       modification. If it is != NULL, the document will be buffered
+ *       and processed through *content_filter, which must set
+ *       csp->content_length and return a modified copy of the body
+ *       or return NULL (on failiure).
+ *     - Changed csp->is_text to the more generic bitmap csp->content_type
+ *       which can currently take the valued CT_TEXT or CT_GIF
+ *     - Reformatting etc
+ *     - Removed all #ifdef PCRS
+ *
  *    Revision 1.23  2001/07/02 02:28:25  iwanttokeepanon
  *    Added "#ifdef ACL_FILES" conditional compilation to line 1291 to exclude
  *    the `block_acl' call.  This prevents a compilation error when the user
