/**
* This method performs the main task of constructing an framework instance and starting its
* execution. The following functions are performed when invoked:
*
* <ol>
* <li><i><b>Examine and verify command-line arguments.</b></i> The launcher accepts a
* "<tt>-b</tt>" command line switch to set the bundle auto-deploy directory and a single
* argument to set the bundle cache directory.
* <li><i><b>Read the system properties file.</b></i> This is a file containing properties to be
* pushed into <tt>System.setProperty()</tt> before starting the framework. This mechanism
* is mainly shorthand for people starting the framework from the command line to avoid
* having to specify a bunch of <tt>-D</tt> system property definitions. The only properties
* defined in this file that will impact the framework's behavior are the those concerning
* setting HTTP proxies, such as <tt>http.proxyHost</tt>, <tt>http.proxyPort</tt>, and
* <tt>http.proxyAuth</tt>. Generally speaking, the framework does not use system properties
* at all.
* <li><i><b>Read the framework's configuration property file.</b></i> This is a file containing
* properties used to configure the framework instance and to pass configuration information
* into bundles installed into the framework instance. The configuration property file is
* called <tt>config.properties</tt> by default and is located in the <tt>conf/</tt>
* directory of the Felix installation directory, which is the parent directory of the
* directory containing the <tt>felix.jar</tt> file. It is possible to use a different
* location for the property file by specifying the desired URL using the
* <tt>felix.config.properties</tt> system property; this should be set using the
* <tt>-D</tt> syntax when executing the JVM. If the <tt>config.properties</tt> file cannot
* be found, then default values are used for all configuration properties. Refer to the <a
* href="Felix.html#Felix(java.util.Map)"><tt>Felix</tt></a> constructor documentation for
* more information on framework configuration properties.
* <li><i><b>Copy configuration properties specified as system properties into the set of
* configuration properties.</b></i> Even though the Felix framework does not consult system
* properties for configuration information, sometimes it is convenient to specify them on
* the command line when launching Felix. To make this possible, the Felix launcher copies
* any configuration properties specified as system properties into the set of configuration
* properties passed into Felix.
* <li><i><b>Add shutdown hook.</b></i> To make sure the framework shutdowns cleanly, the
* launcher installs a shutdown hook; this can be disabled with the
* <tt>felix.shutdown.hook</tt> configuration property.
* <li><i><b>Create and initialize a framework instance.</b></i> The OSGi standard
* <tt>FrameworkFactory</tt> is retrieved from <tt>META-INF/services</tt> and used to create
* a framework instance with the configuration properties.
* <li><i><b>Auto-deploy bundles.</b></i> All bundles in the auto-deploy directory are deployed
* into the framework instance.
* <li><i><b>Start the framework.</b></i> The framework is started and the launcher thread waits
* for the framework to shutdown.
* </ol>
*
* <p>It should be noted that simply starting an instance of the framework is not enough to create
* an interactive session with it. It is necessary to install and start bundles that provide a
* some means to interact with the framework; this is generally done by bundles in the auto-deploy
* directory or specifying an "auto-start" property in the configuration property file. If no
* bundles providing a means to interact with the framework are installed or if the configuration
* property file cannot be found, the framework will appear to be hung or deadlocked. This is not
* the case, it is executing correctly, there is just no way to interact with it.
*
* <p>The launcher provides two ways to deploy bundles into a framework at startup, which have
* associated configuration properties:
*
* <ul>
* <li>Bundle auto-deploy - Automatically deploys all bundles from a specified directory,
* controlled by the following configuration properties:
* <ul>
* <li><tt>felix.auto.deploy.dir</tt> - Specifies the auto-deploy directory from which
* bundles are automatically deploy at framework startup. The default is the
* <tt>bundle/</tt> directory of the current directory.
* <li><tt>felix.auto.deploy.action</tt> - Specifies the auto-deploy actions to be found
* on bundle JAR files found in the auto-deploy directory. The possible actions are
* <tt>install</tt>, <tt>update</tt>, <tt>start</tt>, and <tt>uninstall</tt>. If no
* actions are specified, then the auto-deploy directory is not processed. There is no
* default value for this property.
* </ul>
* <li>Bundle auto-properties - Configuration properties which specify URLs to bundles to
* install/start:
* <ul>
* <li><tt>felix.auto.install.N</tt> - Space-delimited list of bundle URLs to
* automatically install when the framework is started, where <tt>N</tt> is the start
* level into which the bundle will be installed (e.g., felix.auto.install.2).
* <li><tt>felix.auto.start.N</tt> - Space-delimited list of bundle URLs to automatically
* install and start when the framework is started, where <tt>N</tt> is the start
* level into which the bundle will be installed (e.g., felix.auto.start.2).
* </ul>
* </ul>
*
* <p>These properties should be specified in the <tt>config.properties</tt> so that they can be
* processed by the launcher during the framework startup process.
*
* @param args Accepts arguments to set the auto-deploy directory and/or the bundle cache
* directory.
* @throws Exception If an error occurs.
