[pkg-wine-party] Bug#732579: workaround to purge wine

[Francesco Presel <f.presel@alice.it>]

If you have installed and can't therefore remove a version of wine 
affected by this bug, you can work around it by creating a fake 
alternative to wine, and letting then apt remove it while uninstalling wine:

$ sudo update-alternatives --install /usr/bin/wine wine /bin/ls 0
$ sudo apt-get purge wine64

By doing that, I was able to remove the package, and the mock 
alternative also disappeared in the process
