Allows a component to state dependencies on other plugins
class IRequireComponents(Interface): def requires(): """list of component classes that this component depends on"""
The Component classes that are returned by the requires method will be enabled upon environment upgrade. This allows very simple dependencies. Of course, for installation, the required components are still required to be part of python (in install_requires in setup.py) and this plugin will not work if there is trouble loading a plugin that is required.
If you have any issues, create a new ticket.

The files in test.py illustrate how to use the plugin. Enable the ComponentDependencyPlugin (componentdependencies.componentdependency.componentdependencyplugin = enabled) and enable the TestDependencyPlugin (componentdependencies.test.testdependencyplugin = enabled). Trac will then require an upgrade. The FooBarTest component will be enabled in the upgrade.
You can also enable the AutoUpgradePlugin prior to this to allow for automatic upgrades.
