// .NAME vtkMimeTypeStrategy - Abstract interface for an object that can identify the
// MIME type of a resource.
//
// .SECTION Description
// Concrete derivatives of vtkMimeTypeStrategy implement strategies for looking-up the
// MIME type of a resource, given its URI, its content, or both.
//
// .SECTION See Also
// vtkMimeTypes, vtkFileExtensionMimeTypeStrategy.
//
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
