+    longDescription = ''
+      Fvwm is a virtual window manager for the X windows system. It was
+      originally a feeble fork of TWM by Robert Nation in 1993 (fvwm history),
+      and has evolved into the fantastic, fabulous, famous, flexible, and so on,
+      window manager we have today.
+
+      Fvwm is a ICCCM/EWMH compliant and highly configurable floating window
+      manager built primarily using Xlib. Fvwm is configured using a
+      configuration file, which is used to configure most aspects of the window
+      manager including window looks, key bindings, menus, window behavior,
+      additional modules, and more. There is a default configuration file that
+      can be used as a starting point for writing one's own configuration file.
+
+      Fvwm is a light weight window manager and can be configured to be anything
+      from a small sleek window manager to a full featured desktop
+      environment. To get the most out of fvwm, one should be willing to read
+      the documents, and take the time to write a custom configuration file that
+      suites their needs. The manual pages and the fvwm wiki can be used to help
+      learn how to configure fvwm.
