Custom Wine running

wine_run.sh

#!/bin/bash

# Configuration (set through environment variables):
#
# WINEPREFIX   - what prefix to use.
# wine_path    - to use custom location of Wine (e.g. /opt/wine-main).
# wine         - shortcut for the above, to assume /opt/$wine
# wine_cleanup - run some command after wine exits

#
# Notes:
#
# WINEPREFIX this one you most probably need, otherwise, it will fall back to
# default prefix at $HOME/.wine
#
# wine_path should be set if you need custom Wine, otherwise it will fall back to
# default (implicit) Wine, which is a common usage. This is not a Wine env variable,
# but a custom variable used in the script to set a location if needed.
#
# wine can be set without wine_path, to use /opt/$wine location.
#
# Uses wine_env.sh which sets the environment
#

  $wine_cleanup

Updated to use latest Wine which got rid of wine64 binary.
