+/*! \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.
