=head1 NAME

DBIx::DataSource - Database-independant create and drop functions

=head1 SYNOPSIS

  use DBIx::DataSource qw( create_database drop_database );

  create_database( $data_source, $username, $password )
    or warn $DBIx::DataSource::errstr;

  drop_database( $data_source, $username, $password )
    or warn $DBIx::DataSource::errstr;

=head1 DESCRIPTION

This module implements create_database and drop_database functions for
databases.  It aims to provide a common interface to database creation and
deletion regardless of the actual database being used.

Currently supported databases are MySQL and PostgreSQL.  Assistance adding
support for other databases is welcomed and relatively simple - see
L.
