MKHINDEX generates HTML directory listings like the "Option Indexes" functionality of Apache. Other than the Web server, these listings are static. They greatly increase the performance of the Web server if you use it as a file server. MKHINDEX has been tested on Windows XP, Gentoo Linux, and Mac OS X.
