 You may now compile liquidsoap by running "$MAKE".
 In case of significant library update, "$MAKE clean" is needed first.

 If you want a local version of the documentation, run "$MAKE doc".

 Then, perform installation by running "$MAKE install" as root.

 And... have fun!

  cat <<EOMSG
<WARNING>

 The specified user/group ($with_user/$with_group) for running liquidsoap as a daemon
 do not exist, so I won't install log and PID directories.

 For a fully functional liquidsoap installation, please configure again
 with existing user/group. You may use --with-user=<user> --with-group=<group> 
 to override the default.
