trafshow v2.0 -- full screen visualization of the network traffic.

Changes from v1.31:
- fixed bug in bpf read loop;
- fixed some bugs in filter expression parser;
- improved timeout functions in domain resolving;
- now work properly on ppp interfaces (with header compression disabled);
- now work properly under xterm;
- sort traffic by bytes;
- new keyboard functions -- list PageUp, PageDn, Home, End; switch Tab;
- new command line options;
- man page;
- a lot of time passed :-)

Before compile this program edit main Makefile as you need.
To build this program just enter `make' from the trafshow root directory,
to install login as root and just type `make install'.

Writed and tested under BSD/OS v2.0.
