+#  From: Per Bolmstedt <tomten@kol14.com>

+#   AC> If someone has scripts that read input ID3 tags and convert
+#   AC> them to args for lame (which then encodes the tags into the
+#   AC> output files), let me know, too!
+#
+#  This is easy peasy using Perl.  Especially using Chris Nandor's excellent
+#  MP3::Info package (available on CPAN).  Here's a program I just wrote that
+#  I think does what you want.  Invoke it with "<program> <file> [options]"
+#  (where the options can include an output filename), like for example:
+#
+#          lameid3.pl HQ.mp3 LQ.mp3 -fv
+#
+#  (Note how the syntax differs from that of Lame's.)  The program will
+#  extract ID3 tags from the input file and invoke Lame with arguments for
+#  including them.  (This program has not undergone any real testing..)
