RUNNING THE TEST SUITE
----------------------

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.

+
+(3) "????": If a line begins with four question marks, the rest of the line defines

+ matches, the client silently repeats the comparison using the next server
+ line. When the match fails, the client silently proceeds to the next script
+ line with the then-current server output unconsumed.
+
+(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.
-(3) Otherwise, the line is an input line line that is sent to the server. Any

+(6) "<<< ": If a line begin with three '<' characters and a space, the rest of the
+ line is a filename; the content of the file is inserted into the script

+
+(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 equivalent
+ byte value. Any other character following a \ is sent verbatim.
+ The line is sent with a trailing "\r\n".
Here is a simple example:

before proceeding.
