Unfortunately, we don't have any documentation on how to add support for
new capture file types.

The simplest capture file reader is probably the reader for Sun's snoop,
in "wiretap/snoop.c"; you might look at that module, if the test data
files are binary files.

If the test files are text files, with, for example, hex dumps of packet
data, look at "ascend-*.[chyl]", or "toshiba.c".
