Sieve 1.0d3 release notes:
--------------------------

Changes:
	Sievead/Qd:
	   - Structure: Sievead dot locking moved to common directory; now used 
	        by both sievead and qd.
	Qd:
	   - Structure: qd/agent/config.h is now qd/agent/agent_config.h to avoid
            confict with common config.h.
	   - Dot locking implemented (see above).
	   - Envelope info is now passed to sieve execution code.
	   - Now only enough memory is allocated for message header, not entire 
	        message.
	   - tracef() callback implemented.  Logs to syslog.  Set trace level in
            qd/agent/agent_config.h.
	   - Modified header from sieve is delivered, instead of header from 
	        original message.

Current limitations:
	Qd:
	- Forward, reply, and notify callback not yet implemented. (The functions
         currently print a message to the stderr, stating the function name 
         and the parameter values.)
	- Envelope originator must be specified on command line with -f.
