Metacello is a package management system for Monticello that allows users to define configurations and versions for projects. A configuration file specifies the Monticello files, dependencies, and versions used by a project. Metacello is intended for users of a project, not developers, and allows loading projects along with their dependencies and executing code during and after loading. The current version is 1.0-beta.27.4 and there are plans to release 1.0 by the end of the year with improvements to version naming and validation.
