Version 3.00
   *** NOTE ***
   Version 3.00 is a complete rethink/rewrite of the module. Based on
   real-life use of the module, a number of changes were made to
   make the module easier to use and more consistent internally.
   I will not make such a major change again. The Data::NDS::Multisource
   module was overly complex. The simplest (and most useful) parts were
   put in Data::NDS::Multiele. An additional layer of complexity was
   moved to Data::NDS::Multifile. An additional module
   (Data::NDS::Multisource) may be added which will contain most of
   the remaining functionality (though it will be backwards incompatible
   with the original version).
