FILEREF

File references are used by commands like 'save' and 'reload' as a consistent specifier of a game element that is also represented by a file on disk. For example:

  obj:/core
  
is a reference to the object file for the zone /core.

The format of a file reference is much like a URL: "<type>:<path>". Note that <path> is NOT necessarily the pathname of a file on disk, rather it refers to a particular component of the game (usually a zone).
