+      The empty utility provides an interface to execute and/or interact with
+      processes under pseudo-terminal sessions (PTYs). This tool is definitely
+      useful in programming of shell scripts designed to communicate with
+      interactive programs like telnet, ssh, ftp, etc. In some cases empty can
+      be the simplest replacement for TCL/expect or other similar programming
+      tools because empty:
+
+      - can be easily invoked directly from shell prompt or script
+      - does not use TCL, Perl, PHP, Python or anything else as an underlying language
+      - is written entirely in C
+      - has small and simple source code
+      - can easily be ported to almost all UNIX-like systems
