+## usage: w32codec_dl.pl (codec.conf location)
+
+# this script will use MS's codec dl interface as used by MS Media Player
+# to attempt to locate the codecs listed in codecs.conf. It will download
+# them to a directory "codecs/" below the current dir.
+# you will need the libwww-perl stuff and the utility "cabextract"
+# which may be found at http://www.kyz.uklinux.net/cabextract.php3

+# By Tom Lees, 2002. I hereby place this script into the public domain.
