+This is a directory for the kernel streaming components, along with multimedia
+kernel-mode drivers.
+
+Platform components:
+- ks.sys     Kernel Streaming (and AvStream)
+- sysaudio   Filter graph builder (topology?)
+- portcls    Port Class
+- wdmaud     Kernel-mode portion of the MME (Win 3.1-style) driver
+
+Optional drivers:
+- sndblst    Sound Blaster (+ Pro / 16) compatible driver
+- mpu401     MPU-401 MIDI compatible driver
+
+Much of this code exists only as stubs for future implementation.
+
+-Andrew Greenwood
