To contribute/write to the public Kepler SVN repository, you need to apply for an SVN account:

Also what does the SVN username and password refer to? I used the subversion to check out the code from the trunk from the command line but it did not give me an option to configure any such username and password.

If I were to make a custom actor in kepler then according to the documentation I would have to check out the code in the trunk for kepler and then after creating a module for my actor I would have to start coding for my actor (like mentioned in the HelloWorld example). If I have some additional external jars I need for this actor of mine I just import those external jars into my module's build path and start coding for my actor. Please correct my understanding if I am incorrect until this point.

When somebody tries to open a kar file in kepler what goes on in the background while the workflow runs? How are the jars related to this kar identified from within the workflow system? I am trying to see if I can make a custom actor and supply my team member with a kar file for the actor, can he/she import this kar file in kepler and run this actor (without getting any source code checked out and adding any additional jars?)
