File/stream copying with compression and rotation.

Documentation and examples are at homepage, so look there.

Some examples of functionality:

Rotation by time interval or output filesize.

Compression (GZ, BZ2, XZ, LZO).

strftime() on output filename.

PCAP files: each rotated file has correct PCAP header, all the split files can be read with Wireshark etc.

Tee-mode: stdin -> stdout, with the magic underneath outputting to a file(s).

Optional command run on each of the output files.
