+## Execute a shell command specified by @var{string}.
+## If the optional argument @var{type} is "async", the process
+## is started in the background and the process id of the child process
+## is returned immediately.  Otherwise, the process is started and
+## Octave waits until it exits.  If the @var{type} argument is omitted, it
+## defaults to a value of "sync".
+## 
+## If the optional argument @var{return_output} is true and the subprocess
+## is started synchronously, or if @var{shell_cmd} is called with one input
+## argument and one or more output arguments, then the output from the command
+## is returned.  Otherwise, if the subprocess is executed synchronously, its
+## output is sent to the standard output.
+##
+## The @code{shell_cmd} function can return two values.  The first is the
+## exit status of the command and the second is any output from the
+## command that was written to the standard output stream.  For example,
+## 
+## @example
+## [status, output] = shell_cmd ("echo foo; exit 2");
+## @end example
+## 
+## @noindent
+## will set the variable @code{output} to the string @samp{foo}, and the
+## variable @code{status} to the integer @samp{2}.
+## 
+## For commands run asynchronously, @var{status} is the process id of the
+## command shell that is started to run the command.
