// .NAME FileInfo
// .SECTION Description
// FileInfo is a class used to pass data concerning a file's usage. The extent
// does not refer to the extent of the file in relation to the global space
// (although it could (it could refer to any extent depending on the context))
// but to the extent of the file that is of interest.
