MKS Toolkit
MKS Toolkit is a software package produced and maintained by PTC that provides a Unix-like environment for scripting, connectivity and porting Unix and Linux software to Microsoft Windows. It was originally created for MS-DOS, and OS/2 versions were released up to version 4.4. Several editions of each version, such as MKS Toolkit for developers, power users, enterprise developers and interoperability are available, with the enterprise developer edition being the most complete. Before PTC, MKS Toolkit was owned by MKS Inc. In 1999, MKS acquired a company based in Fairfax, Virginia, USA called Datafocus Inc. The Datafocus product NuTCRACKER had included the MKS Toolkit since 1994 as part of its Unix compatibility technology. The MKS Toolkit was also licensed by Microsoft for the first two versions of their Windows Services for Unix, but later dropped in favor of Interix after Microsoft purchased the latter company. Version 10.0 was current . Overview
