+# TODO:
+# - Task colors:
+#     - User-defined using config file.
+#     - Automagically chosen from color space.
+#     - Advanced algorithm (contact Hannes Pretorius).
+# - Koos' specs:
+#     - Resources and tasks sorted in read-in order (default)
+#       or alphabetically (flag).
+#     - Have proper gnuplot behavior on windows/x11, eps/pdf, latex terminals.
+#     - Create and implement algorithm for critical path analysis.
+# - Split generic stuff into a Gantt class, and specific stuff into the main.
