v1.1 of plugin: Adds the win32 ports of Unix command-line utilities to the system32 path. You can delete any commands you don't want/need to save space, of course. Includes a menu entry that opens a command prompt window to the readme (exiting the readme will leave you in the command prompt so you can start using the Unix utilities right away). The readme has basic examples of some of the more common Unix commands.
