+"""
+    This module implements an ncurses frontend for the BitBake utility.
+
+    We have the following windows:
+
+        1.) Title Window: Shows the title, credits, version, etc.
+        2.) Main Window: Shows what we are ultimately building and how far we are.
+        3.) Thread Activity Window: Shows one status line for every concurrent bitbake thread.
+        4.) Command Line Window: Contains an interactive command line where you can interact w/ Bitbake.
+
+    Basic window layout is like that:
+
+        |---------------------------------------------------------|
+        |-                <Title Window>                          |
