+    longDescription = ''
+      The xterm program is a terminal emulator for the X Window System. It
+      provides DEC VT102/VT220 and selected features from higher-level
+      terminals such as VT320/VT420/VT520 (VTxxx). It also provides Tektronix
+      4014 emulation for programs that cannot use the window system directly.
+      If the underlying operating system supports terminal resizing
+      capabilities (for example, the SIGWINCH signal in systems derived from
+      4.3bsd), xterm will use the facilities to notify programs running in the
+      window whenever it is resized.
