+=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<DBIx::DataSource::Driver>.
+
