Note: These commands work with src/XX_name/XX_name.py files and are for TinyTorch contributors/developers. Students use tito module commands to work with generated notebooks.

Directory Structure:

src/              ← Developers edit here (Python source)
modules/          ← Students use these (generated notebooks)
tinytorch/        ← Package code (auto-generated)
