# (!) FIRST RUN for 32 bit:
# WINEARCH=win32 WINEPREFIX=~/wine32 winecfg
# echo 'export WINEPREFIX="$HOME/wine32"' >> ~/.bashrc
# exec $SHELL

# to run under Wayland:
# run commands as 'DISPLAY= wine64 notepad' for 64 bit OR 'DISPLAY= wine notepad' for 32 bit
# xlsclients - lists the applications running under XWayland (thus not native Wayland windows)
# xwininfo - check X window info (shows nothing if it is not X window)

# usage examples:
# wine start /unix path_to_installer
# winefile OR wine explorer
# wine explorer /desktop=name,1024x768 program.exe
# sudo mount -o loop /media/tar/d/games/Unreal\ Turnament\ 2004/ut3.iso /home/tar/cd-rom/three
