Build Automation of K2 Project from TFS

We are working on K2 Blackpearl project (Visual Studio 2010, K2 Blackpearl, SQL Server 2008). we are
using Team Foundation Server to automate our build process. For other projects we are
using MSBuild task to build the project. But for K2 I could find MSBuild command
for Deployment only but for that also first I need to create the K2 deployment
package. How do we automate the creation of the deployment package?  I couldn’t find any K2 dll which Implements
ITask interface for Compilation and Creation of Deployment Package. I found C#
code over internet which suggests to create a library project which will
Compile and Create Deployment package. Is there any way where we can Compile
and Create a Deployment Package using MSBuild command only without any custom
code.
