Release Name: 0.9.13

Notes:



Changes:
  * fixed Warts::File#open to handle paths with spaces and other special
    characters
  * implemented methods to retrieve hop TLV values; namely,
       hop_reply_ipid
       hop_reply_iptos
       hop_next_hop_mtu
       hop_inner_iplen
       hop_inner_ipttl
       hop_inner_iptos
  * implemented Warts::Trace#hop_has_reply_ttl?; you should call this when
    Warts::Trace#hop_reply_ttl returns 0, to distinguish between a true
    0 reply TTL and a missing reply TTL
  * implemented Warts::Trace#hop_has_tcp_reply? and #hop_has_icmp_reply?;
    use these methods to determine which type of reply data is available,
    either ICMP or TCP (these are mutually exclusive); the methods
    Trace#hop_icmp_type, Trace#hop_icmp_code, and Trace#hop_tcp_flags
    now return nil if a reply of the given type isn't available    
  * implemented Warts::Trace#hop_tcp_flags_breakdown
  * implemented Warts::Trace.decompose_tcp_flags and decompose_hop_flags
    convenience methods
  * added Warts::Trace::STOP_REASON_TEXT which is a hash from stop reason
    code to human-oriented text
  * added Warts::Trace#dest and #dest_cmp methods; the previous #dst and
    #dst_cmp methods are still available but deprecated
  * moved Warts::File::TRACE, Warts::File::LIST, Warts::File::CYCLE_START,
    etc. constants to Warts::TRACE, Warts::LIST, etc.; the previous definitions
    are still available, though deprecated
  * added Warts::Trace::HOP_FLAG_TCP
  * changed to export the internal scamper constant SCAMPER_TRACE_STOP_DEAD
    as Warts::Trace::STOP_GAPLIMIT rather than Warts::Trace::STOP_DEAD; this
    is in keeping with recent changes in scamper; the old STOP_DEAD constant
    is still available for backwards compatibility, though deprecated
  * made internal changes needed to build with scamper-cvs-20070523j
  * updated sample scripts to use newest non-deprecated methods; also
    improved stat-traces script to print out TCP flags stats
