This document talks about packaged files.
Packaged files have multiple resources stored in one file. All the resources
in one package are stored in a single file, whose name is specified in
p.packmem. The name may be '\0', in which case the package file itself
is used.
Non-packaged files have one resource per file. The name is specified
in each resource instance info field.
