+
+DBIx::Class::CDBICompat - Class::DBI Compatability layer.
+
+=head1 SYNOPSIS
+
+  use base qw/DBIx::Class/;
+  __PACKAGE__->load_components(qw/CDBICompat Core DB/);
+
+=head1 DESCRIPTION
+
+DBIx::Class features a fully featured compability layer with L<Class::DBI>
+to ease transition for existing CDBI users. In fact, this class is just a
+receipe containing all the features emulated. If you like, you can choose
+which features to emulate by building your own class and loading it like 
+this:
+
+  __PACKAGE__->load_own_components(qw/CDBICompat/);
+
+this will automatically load the features included in My::DB::CDBICompat, 
+provided it looks something like this:
+
+  package My::DB::CDBICompat;
+  __PACKAGE__->load_components(qw/
+    CDBICompat::ColumnGroups
+    CDBICompat::Retrieve
+    CDBICompat::HasA
+    CDBICompat::HasMany
+    CDBICompat::MightHave
+  /);
