IAppInstall

An object representing a specific application (the distribution is a pkg_resource.Distribution object), for the given entry point name in the given group. Right now the only group used for this is 'paste.app_factory'.

Return a text description of the application and its configuration. sys_config is a dictionary representing the system configuration, and can be used for giving more explicit defaults if the application preparation uses the system configuration. It may be None, in which case the description should be more abstract.

Applications are free to ignore sys_config.

Write a fresh config file to filename. command is a paste.script.command.Command object, and should be used for the actual operations. It handles things like simulation and verbosity.

sys_config is (if given) a dictionary of system-wide configuration options.

Set up the application, using command (to ensure simulate, etc). The application is described by the configuration file config_filename. sys_config is the system configuration (though probably the values from it should have already been encorporated into the configuration file).
