+# audiorip
+#
+# Shell script to rip an audio CD-ROM.
+#
+# To use this, first create a directory for the mp3s, and cd to that
+# directory. Then run this script. This script also saves lossless copies of
+# the mp3s in a directory ending with [LL].
+#
+# One of these days I'm going to rewrite this in Ruby or some other language,
+# and include more advanced features, like the ability to rip multiple
+# CD-ROMs at once. For now, this script works, and is a good example of
+# using getopts with bash.
