//! \ingroup OpenMaya MFn
//! \brief Function set for querying information about file references.
/*!
  
  Reference nodes are used to track data about file references. Referenced
  files may be loaded and unloaded. They also store data about changes
  made to objects in the referenced file. The class MItEdits may 
  be used to retrieve information about such changes.

  The class MFileIO may be used to perform actual operations on references
  such as loading, unloading, adding and removing references.
