The source code in this directory was taken from VPNC SVN.
Note that the ISAKMP packet handling code was modified in
order to accomodate encrypted payloads in isakmp_packet
structures.  The inner workings of the parse and flatten
routines were changed accordingly, and some more functions
were exposed in the external interface.
