I would like present you ``Versionner''.�Versionner�is a GUI for metacello. It supports a simple working style, providing a basic UI set to handle versions: (i)create a configuration (ii) update an application (iii) commit and save all the packages of an application (iv) load an application from a repository. The goal of�Versionner, is to not write a metacello version by hand again. Saving and committing all your monticello package, and creating a new metacello version is a one click operation.
