+# Convert the FreePats Drums_000 directory to ITL Chorus drums.tar.bz2
+# Note: technically, this must be run in a directory with subdirectories
+# starting with a MIDI pitch, and containing a text file with a
+# "convert_to_wav:" command that produces a .wav in that working directory.
+# sox is required to convert the audio. This handles the dirt-old options
+# for sox in the text files explicitly to support the FreePats standard.
+# The current version was checked in from the Drums_000 directory to be
+# found in the TAR at this URL:
+# http://freepats.zenvoid.org/samples/freepats/freepats-raw-samples.tar.bz2
+# Thank you again, FreePats!
