*********************
INTRODUCTION
*********************

tooLAME is an optimized Mpeg Audio 1/2 Layer 2 encoder.  It is based heavily on
    - the ISO dist10 code
    - improvement to algorithms as part of the LAME project (www.sulaco.org/mp3)
    - work by Mike Cheng and other contributors (see CONTRIBUTORS)
