ptunnel-ng:
* this is now an autotools project (added/renamed required files e.g. AUTHORS, COPYING) * removed user defined ip header (buggy; not useful anymore)

- * - The seq-no of the ping packet is used in a sliding-window-esque
- * way, and to identify the order of data.
- *
- * The protocol can be in any of the following states:
- * kProxy_start Causes the proxy to open a connection to the given
- * host and port, associating the ID with the socket,
- * before the data on the socket are transmitted.
- * kProxy_data Indicates that the packet contains data from the proxy.
- * Data ordering is indicated by the seq-no, which will start
- * at 0. (The proxy and forwarder maintain different seq-nos.)
- * kUser_data This packet contains user data.
- * kConnection_close Indicates that the connection is being closed.
- * kProxy_ack and Acknowledges the packet (and all packets before it) with seq_no = ack.
- * kUser_ack This is used if there are no implicit acknowledgements due to data
- * being sent.
- *
- * Acknowledgements work by the remote peer acknowledging the last
- * continuous seq no it has received.
- *
- * Note: A proxy receiving a kProxy_data packet, or a user receiving a
- * kUser_data packet, should ignore it, as it is the host operating system
- * actually returning the ping. This is mostly relevant for users, and for
- * proxies running in unprivileged mode.
