Thank you for purchasing MKS Toolkit for Professional Developers or MKS Toolkit for Enterprise Developers. These products contain the tools and libraries to aid you in developing cross-platform solutions using the NuTCRACKER Platform, MKS' award-winning UNIX® compatibility environment on Windows®.

MKS Toolkit for Professional Developers lets you develop, port, migrate and deploy non-graphical UNIX-based applications and scripts.

MKS Toolkit for Enterprise Developers adds support for Motif, X Windows, 3-D, and Open GL giving you a complete solution for cross-platform development, deployment, interoperability, and migration of both graphical and non-graphical UNIX applications and scripts.
