 5 The CVS client/server protocol
 In the following, `\n' refers to a linefeed and `\t' refers to a
 horizontal tab; "requests" are what the client sends and "responses"
 are what the server sends.  In general, the connection is governed by
 the client--the server does not send responses without first receiving
 requests to do so; see  Response intro for more details of this
    It is typical, early in the connection, for the client to transmit a
 `Valid-responses' request, containing all the responses it supports,
 followed by a `valid-requests' request, which elicits from the server a
 `Valid-requests' response containing all the requests it understands.
 In this way, the client and server each find out what the other
 supports before exchanging large amounts of data (such as file
