+=head1 NAME
+
+ZOOM::IRSpy::Stats - statistics generated for IRSpy about its targets
+
+=head1 SYNOPSIS
+
+ $stats = new ZOOM::IRSpy::Stats($dbname);
+ use Data::Dumper; print Dumper($stats);
+
+=head1 DESCRIPTION
+
+Provides a simple API to obtaining statistics about targets registered
+in IRSpy.  This is done just by creating a Stats object.  Once this
+object is made, it can be crudely dumped, or the application can walk
+the structure to produce nice output.
+
+=head1 METHODS
+
+=head2 new()
+
+ $stats = new ZOOM::IRSpy::Stats($dbname, "dc.creator=wedel");
+ # Or:
+ $stats = new ZOOM::IRSpy::Stats($dbname,
+         new ZOOM::Query::PQF('@attr 1=1003 wedel');
+ # Or:
+ $spy = new ZOOM::IRSpy("target/string/for/irspy/database"); 
+ $stats = new ZOOM::IRSpy::Stats($spy, $query);
+
+Creates a new C<ZOOM::IRSpy::Stats> object and populates it with
+statistics for the targets in the nominated database.  This process
+involves analysing the nominated IRSpy database at some length, and
+which therefore takes some time
+
+Either one or two arguments are required:
+
+=over 4
+
+=item $irspy (mandatory)
+
+An indication of the IRSpy database that statistics are required for.
+This may be in the form of a C<ZOOM::IRSpy> object or a database-name
+string such as C<localhost:3313/IR-Explain---1>.
+
+=item $query (optional)
+
+The query with which to select a subset of the database to be
+analysed.  This may be in the form of a C<ZOOM::Query> object (using
+any of the supported subclasses) or a CQL string.  If this is omitted,
+then all records in the database are included in the generated
+statistics.
