From Wipro Technologies:
UWIN is a Unix to Windows Migration Toolkit that gives you all the features of a traditional UNIX operating system on Windows NT and Windows 95/98. This release of UWIN supports new functionality (as documented in the What's New section) and new libraries and utilities. It has an improved performance, and provides better interoperability with other file systems such as Samba. Features of UWIN also include pipes, hard file links, UNIX networking, and UNIX graphical support through the X Window System. It also provides UNIX and POSIX.2 utilities such as Ksh, awk, and vi. The UWIN environment is a user-mode runtime library, which works over the Win32 sub-system. Shell scripts and other scripted applications that use UNIX and POSIX.2 utilities will run under UWIN. Support is also provided for working on a Windows NT system remotely through a Telnet Session. This version contains many new bug fixes, enhancements, and utilities.
