Class Summary


    $db =
      Bio::EnsEMBL::DBLoader-\>new( "Bio::EnsEMBL::DBSQL::DBAdaptor/"
        . "host=localhost;"
        . "dbname=homo_sapiens_core_19_34a;"
        . "user=ensro;" );

    # $db is a database object
    $db = Bio::EnsEMBL::DBLoader-\>standard();

    # equivalent to
    # Bio::EnsEMBL::DBLoader-\>new( $ENV{'ENSEMBL_DATABASE'} );


This system provides a run-time loading of the database for ensembl,
allowing two things
    a) Only "using" the database module which is required for a
       particular implementation
    b) Providing a simple string method to indicate where the database
       is, allowing per sites defaults and other things as such
The string is parsed as follows:
Before the / is the Perl database object to load, after are the
parameters to pass to that database.  The parameters are series of
key=values separated by semi-colons.  These are passed as a hash to the
new method of the database object
