+DBIx::Class::DB - Simple DBIx::Class Database connection by class inheritance
+
+=head1 SYNOPSIS
+
+  package MyDB;
+
+  use base qw/DBIx::Class/;
+  __PACKAGE__->load_components('DB');
+
+  __PACKAGE__->connection('dbi:...', 'user', 'pass', \%attrs);

+  use base qw/MyDB/;
+  __PACKAGE__->load_components('Core'); # just load this in MyDB if it will always be there

+
+=head1 DESCRIPTION
+
+This class provides a simple way of specifying a database connection.
+
+=head1 METHODS
+
+=head2 storage
+
+Sets or gets the storage backend. Defaults to L<DBIx::Class::Storage::DBI>.
+
+=head2 class_resolver
+
+Sets or gets the class to use for resolving a class. Defaults to 
+L<DBIx::Class::ClassResolver::Passthrough>, which returns whatever you give
+it. See resolve_class below.
