12  * Interface for managing files uploaded to Roller.

14  * NOTE: this should probably be renamed "ResourceManager" or similar
15  * since the real jobe here is managing resources, not just files. We should
16  * then extend this a bit more to include the notion of not only user uploaded
17  * resources, but also other resources the system stores, such as the blacklist.
