### Code Practices

- All macros and constants in caps: `MAX_BUFFER_SIZE`, `TRACKING_ID_PREFIX`.
- Struct names and typedef's in camelcase: `GtkWidget`, `TrackingOrder`.
- Functions that operate on structs: classic C style: `gtk_widget_show()`,
  `tracking_order_process()`.
- Pointers: nothing fancy here: `GtkWidget *foo`, `TrackingOrder *bar`.
- Global variables: just don't use global variables. They are evil.
- Functions that are there, but shouldn't be called directly, or have obscure uses, or
  whatever: one or more underscores at the beginning: `_refrobnicate_data_tables()`,
  `_destroy_cache()`.
