Active Maker is a utility for building and managing multiple
cross-referenced Microsoft Visual Basic projects.
It minimizes development time by tracking the projects'
cross-references automatically.
Active Maker is designed to dramatically reduce time and
effort in large MS Visual Basic projects development. Using Active Maker
in complex projects (more than 30 components) saves up to 15-25% of integration
and sustaining effort.
