+Mishell provides an interactive console
+that executes scripts in different scripting languages.
+Running mishell: 
+- Standalone: 
+Mishell can be run directly with the "java -jar ${artifactId}-${version}.jar" idiom or as
an OSGi bundle. Remember that in both cases
+JRE 6 is needed. Mishell provides some built-in commands and interprets ruby, javascript
or any other language that you
+configure. You can also load scripts with the load command. Type 'help' for available commands.

+- Inside OSGi: 
+You can see an example of configuring Felix for launching both Jmood and mishell in the same
OSGi platform in the FelixLauncher
+class in the src/test/java dir. Remember to change the paths to match your installation.

+
+The initial object that is exported to the scripting engine is a JMoodProxyManager that extends

+the general-purpose MBeanProxyManager (from the jmxintrospector project) to simplify working
with JMood. 
+For example, when running on OSGi with JMood you can add the mbeans by typing:
+$manager.addLocalServer(nil) #Ruby
+or
+manager.addLocalServer(null) //Javascript
+And you issue commands like
+$manager.objects.each{|mbean| puts mbean.objectName} #this lists the objectnames for all
mbeans known to the shell
+
+
+
+
+IMPORTANT: 
+Dependencies that need to be manually installed:
+1. It needs Java 6 to work (as it depends on javax.script API). 
+Once that API is stable and released standalone, it should also work in Java 5.
+2. It needs JMX introspector which in turn needs Javassist to be 
+manually installed in your local maven repo.
+3. It needs both the jruby-javax.script binding and Jruby 0.9 to be manually 
+installed in the M2_REPO. 
+	- The binding is available at https://scripting.dev.java.net/ and licensed
+	under the BSD license. Download the jsr223-engines.[zip|tar.gz]
+	and install the  jruby-engine.jar
+	- JRuby is available at http://dist.codehaus.org/jruby/ under a tri-license: CPL/LGPL/GPL
+	located at engines/jruby/build/jruby-engine.jar. JRuby implementation
+4. If you want to use any other language, you should: 
+	- Install the binding and the implementation in M2_REPO. Use Jruby as an example to do it.

+	- Add the dependencies to the pom.
