A RCSComp.T, or file differ, is the thread that analyzes the client
and server versions of each possibly-modified file, and determines
what changes must be applied to the file on the client side.
proto describes the version of the protcol being used.
rd is the input stream from the client's Detailer. It provides
details from the client's version of the file.
wr is the output stream to the client's Updater. The file differ
writes edit requests to this stream in order to effect file updates
on the client.
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 RCSComp.
