  # This script attempts to install Speex, which is needed by someone who wants
  # to enable audio compression when doing online decoding.
  #
  # Note: This script installs Speex in a non-standard position and leads the test 
  # procedure of Speex give out errors. Those errors will not influence the 
  # installation acutally. So you can ignore them and call Speex's library correctly.
  # I just let it be like this at this moment, and may add a patch to resolve this
  # later.
