  * Description :  Apply all jobs from the joblist (aka. Perl regexp's) to
- *                the text buffer that's been accumulated in csp->iob->buf.
- *                Then, write the modified buffer out to the client
- *                (Maybe this should happen from jcc.c via flush_socket
- *                for better readability).

+ *                and set csp->content_length to the modified size.
  *
  * Parameters  :
  *          1  :  csp = Current client state (buffers, headers, etc...)
  *
- * Returns     :  N/A
+ * Returns     :  a pointer to the (newly allocated) modified buffer.
