CLIENT SCRIPTS

-Lines in client scripts are of two kinds:
+Lines in client scripts are of several kinds:
(1) If a line begins with three question marks and a space, the rest of the
line defines the start of expected output from the server. If what is
received does not match, the client bombs out with an error message.
-(2) If a line starts with three plus signs followed by a space, the rest of the

+(3) If a line begins with four question marks, the rest of the line defines
+ the start of one or more possible output lines from the server. When it

+(4) If a line starts with three plus signs followed by a space, the rest of the
line specifies a number of seconds to sleep for before proceeding.

-(5) Otherwise, the line is an input line line that is sent to the server. Any
+(7) Otherwise, the line is an input line line that is sent to the server. Any
occurrences of \r and \n in the line are turned into carriage return and
linefeed, respectively. This is used for testing PIPELINING.
Any sequences of \x followed by two hex digits are converted to the equvalent
