* 1. A value will be gotten by @{link BundleContext#getProperty(key)} with

* The value will be used for the referal URL. Under the url, there must be a simple
* bundles list file to be installed with thier start level and flag of marked as started.
*
* 2. If the value is null, do nothing any more.
* 3. Otherwise, retrieve the bundles list from the url and install,

* 4. A value will be gotten by @{link BundleContext#getProperty(key)} with
