A TreeComp.T, or tree differ, represents the thread that compares
the client and server file trees, and determines which files are
missing, extra, or possibly out-of-date on the client.
proto describes the version of the protocol being used.
rd is the input stream from the client's Tree Lister.
wr is the output stream to the client's Detailer.
collections is a sequence of supfile records, specifying which
collections and releases are to be transferred.
compLevel is the compression level to be used, for collections that
have compression enabled.
If a reaper is given, it will be notified just before the thread
terminates.
VAR traceLevel := 0;
END TreeComp.
