     3== Description ==
     4
     5ComponentDependencyPlugin allows a `Component` to state a dependency on other plugin, via the `IRequireComponents` interface:
     6
     7{{{
     8class IRequireComponents(Interface):
     9    def requires():
     10        """list of component classes that this component depends on"""
     11}}}
     12
     13The `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.

     28
     29You can check out ComponentDependencyPlugin from [http://trac-hacks.org/svn/componentdependencyplugin here] using Subversion, or [source:componentdependencyplugin browse the source] with Trac.
     30
     31== Example ==
     32
     33The 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.
