naturally expect them to. You'd type "sna.th.fid == 0xf" to find Adjacent
Subarea Nodes. The user does not have to shift the value of the FID to
the high nibble of the byte ("sna.th.fid == 0xf0") as was necessary
before Wireshark 0.7.6.

is an overly-complicated example of how to use it. I don't recommend
looking at it as a guide; instead, the API description here should be good
