"""The ``command_stack`` module provides tools for managing and
executing stacks of :class:`~hooke.engine.CommandMessage`\s.
+
+In experiment analysis, the goal is to construct a
+:class:`~hooke.command_stack.CommandStack` that starts with your raw
+experiment data and ends with your analyzed results. These
+:class:`~hooke.command_stack.CommandStack`\s are stored in your
+:class:`~hooke.playlist.FilePlaylist`, so they are saved to disk with
+the analysis results. This means you will always have a record of
+exactly how you processed the raw data to produce your analysis
+results, which makes it easy to audit your approach or go back and
+reanalyze older data.
