The build system uses only the first argument in the list
as the package manager when creating your image or SDK.
However, packages will be created using any additional
packaging classes you specify.
For example, if you use the following in your

<literallayout class='monospaced'>
PACKAGE_CLASSES ?= "package_ipk package_tar"

The OpenEmbedded build system uses the IPK package manager
to create your image or SDK as well as generating
TAR packages.
