util/
The util directory contains code that
- Provides useful functionality that could be used by more than one library in this module
- Doesn't fall into an existing specialized category, like logging
- Has a relatively limited scope. "Limited scope" is a subjective criteria. If there are many objects and functions that all interact together, consider placing the code in its own top-level directory and not here.
