The Heat Template

The heat template is where most of the real work happens. The result of the Heat

The Template Definition
|
||||
-----------------------
|
||||
|
||||
Template definitions are a mapping of Magnum object attributes and Heat template
|
||||
parameters, along with Magnum consumable template outputs. Each definition also
|
||||
denotes which Bay Types it can provide. Bay Types are how Magnum determines which
|
||||
of the enabled Template Definitions it will use for a given Bay.

The Definition Entry Point
|

--------------------------
|

|

Entry points are a standard discovery and import mechanism for Python objects.
|
||||
Each Template Definition should have an Entry Point in the `magnum.template_definitions`
|
||||
group. This example exposes it's Template Definition as `example_template = example_template:ExampleTemplate`
|
||||
in the `magnum.template_definitions` group.
