 /*! \class TEPty
 
     \brief Ptys provide a pseudo terminal connection to a program.
 
     Although closely related to pipes, these pseudo terminal connections have
     some ability, that makes it nessesary to uses them. Most importent, they
     know about changing screen sizes and UNIX job control.
 
     Within the terminal emulation framework, this class represents the
     host side of the terminal together with the connecting serial line.
 
     One can create many instances of this class within a program.
     As a side effect of using this class, a signal(2) handler is
     installed on SIGCHLD.
 
     \par FIXME
 
     [NOTE: much of the technical stuff below will be replaced by forkpty.]
 
     publish the SIGCHLD signal if not related to an instance.
 
     clearify TEPty::done vs. TEPty::~TEPty semantics.
