Detailed Description

Synopsis

$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'} );

Description

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
