+Apache Sling Commons Scheduler
+
+The commons scheduler provides a scheduling services which allows to schedule
+tasks periodically.
+
+Disclaimer
+==========
+Apache Sling is an effort undergoing incubation at The Apache Software Foundation (ASF),
+sponsored by the Apache Jackrabbit PMC. Incubation is required of all newly accepted
+projects until a further review indicates that the infrastructure, communications,
+and decision making process have stabilized in a manner consistent with other
+successful ASF projects. While incubation status is not necessarily a reflection of
+the completeness or stability of the code, it does indicate that the project has yet
+to be fully endorsed by the ASF.
+
+Getting Started
+===============
+
+This component uses a Maven 2 (http://maven.apache.org/) build
+environment. It requires a Java 5 JDK (or higher) and Maven (http://maven.apache.org/)
+2.0.7 or later. We recommend to use the latest Maven version.
+
+If you have Maven 2 installed, you can compile and
+package the jar using the following command:
+
+ mvn package
+
+See the Maven 2 documentation for other build features.
+
+The latest source code for this component is available in the
+Subversion (http://subversion.tigris.org/) source repository of
+the Apache Software Foundation. If you have Subversion installed,
+you can checkout the latest source using the following command:
+
+ svn checkout http://svn.apache.org/repos/asf/incubator/sling/trunk/commons/scheduler
+
+See the Subversion documentation for other source control features.

+Apache Sling is an effort undergoing incubation at The Apache Software Foundation (ASF),
+sponsored by the Apache Jackrabbit PMC. Incubation is required of all newly accepted
+projects until a further review indicates that the infrastructure, communications,
+and decision making process have stabilized in a manner consistent with other
+successful ASF projects. While incubation status is not necessarily a reflection of
+the completeness or stability of the code, it does indicate that the project has yet
