+# \brief This module provides the task panel code for the SelectPlane tool.
+
+import FreeCADGui as Gui
+
+# As it is right now this code only loads the task panel .ui file.
+# All logic on how to use the widgets is located in the GuiCommand class
+# itself.
+# On the other hand, the newer tools introduced in v0.19 like OrthoArray,
+# PolarArray, and CircularArray include the logic and manipulation
+# of the widgets in this task panel class.
+# In addition, the task panel code launches the actual function
+# using the delayed mechanism defined by the `todo.ToDo` class.
+# Therefore, at some point this class should be refactored
+# to be more similar to OrthoArray and the new tools.
