  initiate
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
 
 This introduces support for specifying optional IKE SA specific
 source and remote address for child sa initiation. This allows
 to initiate wildcard connection for known address via vici.
 
-In addition this allows impler implementation of trap-any patches
+In addition this allows simpler implementation of trap-any patches
 and is a prerequisite for dmvpn support.
