Library units are similar to C's 'file scope'.  If you declare a unit
(package, subprogram, etc.) and it is NOT nested within another 
unit. then it is a library unit.

e.g. the following file:

	  package library_unit is
	    procedure not_library_unit;
	    package also_not_library_unit is
	      procedure very_much_not_library_unit;
	    end...
	  end library_unit;

	  procedure library_unit_too;

Personally, I try to only have packages as library units.  Declaring
subprograms at the 'library unit' level pollutes the namespace.
