Liferay 6: Deployment/Undeployment with Ext plugins environment

I have always liked the concept of plug-in in Liferay but using the ext environment as plug-in in Liferay 6 seems to be a little bit painful and time taking. It will need you to restart tomcat a couple of times if you are working in service files. The original  post which i used here for reference documents everything.  I am copying it here so that i can recall it in future. However i am listing below the major steps followed in the original post.

1. Stop the tomcat.
2. Remove ext plug-in related jars in @temp folder of your tomcat instance @temp\liferay\com\liferay\portal\deploy\dependencies
3. Remove ext plug-in related jars from ROOT/WEB-INF/lib/
4. Remove xml for ext plug-in from ROOT/WEB-INF/
5. Remove service jar from @tomcat/lib/ext related to plug-in
6. Start tomcat  and deploy updated plug-in war while tomcat is running, You will see a message like  "You must reboot the server and redeploy all other plugin". 
7. Now stop the tomcat and restart it again for the global jars to take effect. And you are ready to go

In the original post you will see the bat script which can be quite handy.
