Within each bundle, there may be a file called bundle.py. It can be used to add dependencies and such to all items with a given tag (see items.py for a general introduction to these concepts).

Here's an example:

tags = {
    'foo': {
        'needs': {
        'triggers': {

With this, whenever you add the foo tag to an item in items.py, that item will also depend on svc_systemd:bar and trigger action:baz.

Supported item attributes are: * needs * needed_by * precedes * preceded_by * tags * triggers * triggered_by

See Selectors for a complete overview of the ways to specify items here.
