-
-The \module{pty} module defines operations for handling the
-pseudo-terminal concept: starting another process and being able to
-write to and read from its controlling terminal programmatically.
-
-Because pseudo-terminal handling is highly platform dependant, there
-is code to do it only for SGI and Linux. (The Linux code is supposed
-to work on other platforms, but hasn't been tested yet.)
-
-The \module{pty} module defines the following functions:
-
-\begin{funcdesc}{fork}{}
-Fork. Connect the child's controlling terminal to a pseudo-terminal.
-Return value is \code{(\var{pid}, \var{fd})}. Note that the child 
-gets \var{pid} 0, and the \var{fd} is \emph{invalid}. The parent's
-return value is the \var{pid} of the child, and \var{fd} is a file
-descriptor connected to the child's controlling terminal (and also
-to the child's standard input and output).
-\end{funcdesc}
-
-\begin{funcdesc}{openpty}{}
-Open a new pseudo-terminal pair, using \function{os.openpty()} if
-possible, or emulation code for SGI and generic \UNIX{} systems.
-Return a pair of file descriptors \code{(\var{master}, \var{slave})},
-for the master and the slave end, respectively.
-\end{funcdesc}
-
-\begin{funcdesc}{spawn}{argv\optional{, master_read\optional{, stdin_read}}}
-Spawn a process, and connect its controlling terminal with the current 
-process's standard io. This is often used to baffle programs which
-insist on reading from the controlling terminal.
-
-The functions \var{master_read} and \var{stdin_read} should be
-functions which read from a file-descriptor. The defaults try to read
-1024 bytes each time they are called.
-\end{funcdesc}
