more user friendly installation and deployment of SharePoint 2007 solution files to a SharePoint server farm. Distribute your SharePoint solution files with this installation program instead of a raw script using STSADM.EXE to install and deploy the solution.
Just notice we can package our .wsp to become exe, so we no need run the stsadm and few more step need to do only can deploy our solution.
codeplex have offer the easy way for us to convert the .wsp to exe, which mean your admin/customer no need know the stsadm command also can install with click next !! :D
