+/*! \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.
+ check if pty is restartable via run after done.
+
+ \par Pseudo terminals
+
+ Pseudo terminals are a unique feature of UNIX, and always come in form of
+ pairs of devices (/dev/ptyXX and /dev/ttyXX), which are connected to each
+ other by the operating system. One may think of them as two serial devices
+ linked by a null-modem cable. Being based on devices the number of
+ simultanous instances of this class is (globally) limited by the number of
+ those device pairs, which is 256.
+
+ Another technic are UNIX 98 PTY's. These are supported also, and prefered
+ over the (obsolete) predecessor.
+
+ There's a sinister ioctl(2), signal(2) and job control stuff
+ nessesary to make everything work as it should.
