*Hot deployment*: Karaf supports hot deployment of OSGi bundles by monitoring jar files inside
the {{\[home\]/deploy}} directory.  Each time a jar is copied in this folder, it will be installed
inside the runtime.  You can then update or delete it and changes will be handled automatically.
 In addition, the Karaf also supports exploded bundles and custom deployers (blueprint and
spring ones are included by default). <br>* *Dynamic configuration*: Services are usually
configured through the ConfigurationAdmin OSGi service.  Such configuration can be defined
in Karaf using property files inside the {{\[home\]/etc}} directory.  These configurations
are monitored and changes on the properties files will be propagated to the services. <br>*
*Logging System*: using a centralized logging back end supported by Log4J, Karaf supports
a number of different APIs (JDK 1.4, JCL, SLF4J, Avalon, Tomcat, OSGi) <br>* *Provisioning*:
Provisioning of libraries or applications can be done through a number of different ways,
by which they will be downloaded locally, installed and started. <br>* *Native OS integration*:
Karaf can be integrated into your own Operating System as a service so that the lifecycle
will be bound to your Operating System. <br>* *Extensible Shell console*: Karaf features
a nice text console where you can manage the services, install new applications or libraries
and manage their state.  This shell is easily extensible by deploying new commands dynamically
along with new features or applications. <br>* *Remote access*: use any SSH client to
connect to Karaf and issue commands in the console <br>* *Security framework* based
on JAAS <br>* *Managing instances*: Karaf provides simple commands for managing multiple
instances. You can easily create, delete, start and stop instances of Karaf through the console.
<br>* Supports the latest OSGi 4.2 containers: Apache Felix Framework 2.0.0 and Eclipse
