+COMMENT(!MOD!zsh/zpty
+A builtin for starting a command in a pseudo-terminal.
+!MOD!)
+The tt(zsh/zpty) module offers one builtin:
+
+startitem()
+findex(zpty)
+xitem(tt(zpty) [ tt(-e) ] [ tt(-b) ] var(name) var(command) [ var(args ...) ])
+xitem(tt(zpty) tt(-d) [ var(names) ... ])
+xitem(tt(zpty) tt(-w) [ tt(-n) ] var(name) var(strings ...))
+xitem(tt(zpty) tt(-r) var(name) [ var(param) [ var(pattern) ] ])
+item(tt(zpty) [ tt(-L) ])(
+In the first form, the var(command) is started with the var(args) as
+arguments. After this, the var(name) can be used in further calls to
+tt(zpty) to refer to this command. With the tt(-e) option given, the
+pseudo-terminal will be set up so that input characters are echoed and 
+with the tt(-b) option given, input and output from and to the
+pseudo-terminal will be blocking.
+
+The second form with the tt(-d) option is used to delete commands
+started before by giving their var(names). If no var(names) are given, 
+all commands are deleted. Deleting a command makes the HUP signal be
+sent to the process started for it.
+
+The tt(-w) option can be used to sent the command var(name) the given
+var(strings) as input (separated by spaces). If the tt(-n) option is
+not given, a newline will be sent after the last var(string).
+
+The tt(-r) option can be used to read the output of the command
+var(name). Without a var(param) argument, the string read will be
+printed to standard output. With a var(param) argument, the string
+read will be put in the parameter named var(param). If the
+var(pattern) is also given, output will be read until the whole string 
+read matches the var(pattern).
+
+The last form without any arguments is used to list the commands
+currently defined. If the tt(-L) option is given, this is done in the
+form of calls to the tt(zpty) builtin.
