Note that the Ethereal distribution also comes with Tethereal and
editcap.
Expand the list of OSes on which Ethereal has (at least at one time)
been built and used.
Note that systems other than Solaris that use DLPI (e.g., HP-UX) may
also have "/dev" entries that can be made more widely readable and
writable to allow non-root users to capture packets.
Note that we can read "i4btrace" capture files.
Note that we now always do SNMP dissection, and that an external library
just allows us to do more sophisticated dissection.
