[Mono-dev] Porting to linux - replacement for winmm.dll

[Manuel de la Pena]

I though you did have to pay any royalties if you are doing the  
following:

# Can I use LAME in my commercial program?
#
# Yes, you can, under the restrictions of the LGPL.  The easiest
# way to do this is to:
#
#1. Link to LAME as separate library (libmp3lame.a on unix or
#  lame_enc.dll on windows)
#
#2. Fully acknowledge that you are using LAME, and give a link
#   to our web site, www.mp3dev.org
#
#3. If you make modifications to LAME, you *must* release these
#   these modifications back to the LAME project, under the LGPL.

#
# *** IMPORTANT NOTE ***
#
# The decoding functions provided in LAME use the mpglib decoding  
engine which
# is under the GPL.  They may not be used by any program not released  
under the
# GPL unless you obtain such permission from the MPG123 project  
(www.mpg123.de).

I understand that you want not to add any extra software, but  
wouldn't adding a implementation of any kind, that also means one  
implemented in C# alone, make you pay anyway??
