r"""Data structures representing Mozilla's source tree.

The frontend files are parsed into static data structures. These data
structures are defined in this module.

All data structures of interest are children of the TreeMetadata class.

Logic for populating these data structures is not defined in this class.
Instead, what we have here are dumb container classes. The emitter module
contains the code for converting executed mozbuild files into these data
