code/modules/cargo/exports.dm 
| /proc/init_export | Makes sure the exports list is populated and that the report isn't null. |
|---|---|
| /proc/export_single_item | It works like export_item_and_contents(), however it ignores the contents. Meaning only exported_atom will be valued. |
| /proc/_export_loop | The main bit responsible for selling the item. Shared by export_single_item() and export_item_and_contents() |
| /proc/setupExports | Called when the global exports_list is empty, and sets it up. |
