"""A file's readers are the entries that resolve to it, not those sharing its name.
The site joined database files to emulators and platforms by bare name. The
collection holds the pak0.pk3 of Quake III and of Enemy Territory; each page
named every engine that reads a pak0.pk3 as a reader of both, which is the
homonym tests/test_game_data_homonyms.py forbids the resolver to serve.
