The goal of Matchstick is to create a framework for the development of high-quality large-scale Apache/mod_perl applications. Projects which use Matchstick will be easier to administrate, from installation to configuration to upgrade.
A more elaborate project description was posted on the Krang mailing-list, back before Perrin Harkins came up with a better name:
The short version is that Matchstick aims to take everything from Krang that isn't specific to creating a content-management system and repackage it for reuse. That means build, installation, upgrade, startup, shutdown, documentation, testing, etc.
