echoping now uses a numbering scheme analog to the
Linux kernel one's. Even versions like 2.2 are stable (or supposed to),
odd versions like 2.1 are unstable, beta.

2.2 :
        Stable release, apart from ICP

2.0.1 -> 2.1.0 :
	Timeouts even on TCP connections.
	Support of HTTP 1.1
	
2.0.0 -> 2.0.1 :

	Bug with getservbyname for HTTP connections fixed.
	
1.3 -> 2.0.0 :
	HTTP support. For testing of Web servers and Web proxies.
	Much better portability.
