sudo apt-get install wine
sudo adduser --disabled-login --shell /usr/sbin/nologin --home /opt/wineshare wineshare
sudo usermod -u 499 wineshare
# define which users can administrate (become root)
User_Alias ADMIN = %admin

# define which users can run the wine/windows programs
User_Alias WINDOWS_USERS = ALL

# define which commands the WINDOWS_USERS may run
Cmnd_Alias WINDOWS = /usr/bin/wine,/usr/bin/winecfg

# Defaults
Defaults:WINDOWS_USERS env_reset
Defaults:WINDOWS_USERS env_keep += DISPLAY
Defaults:WINDOWS_USERS env_keep += XAUTHORITY

# Members of the admin user_alias, defined above,  may gain root privileges
ADMIN ALL=(ALL) ALL

# The WINDOWS_USERS may run WINDOWS programs as user windows without a password
WINDOWS_USERS ALL = (wineshare) NOPASSWD: WINDOWS
