+Creature Action Sounds for Freedoom - G. Wessner "Stilgar"
+				 (masterstilgar@yahoo.com)
+
+Sound effects recorded by myself via microphone and audio
+manipulation software.  I hereby allow the Freedoom project to
+use these audio files under the Freedoom license.
+
+DSBGACT and DSDMACT are the main additions in this .zip.  DSBGACT
+is a hiss type sound, to go with the snake-imp, while DSDMACT is
+a "generic" growl, since it is used by a variety of creatures.
+
+spare_death.wav is an extra.  I recorded it intending to make a
+player death sound for "DSPDIEHI", but after testing I don't think
+it fits that slot very well.  I'm including it anyways since I don't
+think it is a bad sound in its own right. If it is deemed useful
+somewhere, please do slot it in, otherwise feel free to make it
+available on the "attic" area.
