These tty utility functions are non-standard. They usually
are available on BSD and/or glibc based systems.

+	  Provide a libutil library.
+	  This non-standard conforming library provides the following
+	  utility functions:
+
+	  forkpty(): combines openpty(), fork(2), and login_tty() to
+	               create a new process operating in a pseudo-terminal.
+	  login(): write utmp and wtmp entries
+	  login_tty(): prepares for a login on the tty fd by creating a
+	               new session, making fd the controlling terminal for
+	               the calling process, setting fd to be the standard
+	               input, output, and error streams of the current
+	               process, and closing fd.
+	  logout(): write utmp and wtmp entries
+	  logwtmp(): constructs a utmp structure and calls updwtmp() to
+	               append the structure to the utmp file.
+	  openpty(): finds an available pseudo-terminal and returns
+	               file descriptors for the master and slave
+
+	  This library adds about 3k-4k to your system.
