AirPlay to Logitech Media Server bridge

This is a fork from https://github.com/disaster123/shairport2_plugin with the following changes

• works under Windows as well
• has a build-in mDNS server (the part below related to avahi does not apply anymore, or at least is not needed)
• allows audio to be sent to LMS sync'd players
• does not require (normally) any extra installation of Perl addons

It is now part of LMS' 3rd party repositories, see support thread here

Please see here to know how to rebuild my apps in general

Otherwise, you can just get the source code and pre-built binaries:

cd ~
git clone http://github.com/philippe44/lms-shairtunes2w
cd ~/lms-shairtunes2w
git submodule update --init

and build doing:

cd ~/lms-shairtunes2w/application
make
