 ** Abstract **
 
-odhcp6c is a minimal DHCPv6 and RA-client for use in embedded Linux systems.
+odhcp6c is a minimal DHCPv6 and RA-client for use in embedded Linux systems
+especially routers. It compiles to only about 30 KB (-Os -s).
 
 
 ** Features **
 
-1. Handling of non-temporary addresses
-	a) assignment of addresses to source interface
-	b) handling of valid and preferred lifetimes
-	c) duplicate address detection
+1. IPv6 bootstrap from different environments with autodetection
+	a) RA only
+	b) RA + stateless DHCPv6
+	c) RA + stateful DHCPv6 (either IA_NA or IA_PD or both)
 
-2. Support for DHCPv6 extension
+2. Handling of non-temporary addresses (IA_NA)
+	a) handling of valid and preferred lifetimes
+	b) automatic fallback to stateless or PD-only mode
+
+3. Support for DHCPv6 extension
 	a) Reconfigure-Messages
-	b) Prefix Delegation
+	b) Prefix Delegation (including handling of valid and preferred lifetimes)
 	c) Prefix Exclusion
 	d) DNS Configuration Options
 	e) NTP Options
 	f) SIP Options
+	g) Information-Refresh Options
+	h) Configurable SOL_MAX_RT
+	i) DS-Lite AFTR-Name Option
 
-3. Stateless fallback-support

-4. State script support

-5. Support for requesting and parsing Router Advertisements
+4. Support for requesting and parsing Router Advertisements
 	a) parsing of prefixes, routes, MTU and RDNSS options
