# REQUIREMENTS:

# - Arch Linux or equivalent (uses pacman)
#
# - Existing PlayonLinux package installation and $HOME/.PlayOnLinux folder
# with all relevant subfolders
#
# - git, sudo, pwd...etc.
#
# - dxvk-git and wine-staging-git package dependencies installed
# (see PKGBUILD files ./PKGBUILD and ./0-dxvk-git/PKGBUILD for details)
#
# - Internet connection
#
# - GPU Vulkan support and the most recent Nvidia/AMD drivers

###########################################################

# Usage

# Run with sudo
#
# # sudo bash ./updatewine.sh
#
# NOTE: All commands are executed as user (defined above).
# Only commands which require root permissions are ones
# which install packages wine-staging-git and dxvk into
# your system

# All regular user commands have prefix 'cmd' below

# Switches:
#
#   --refresh
#
#       Check for new Staging/DXVK releases, update PoL Wine prefixes if needed
#       Does a comparison between local & remote git repos
#
#   --check
#
#       Check for new Staging/DXVK releases
#       Does a comparison between local & remote git repos
#
#   --force
#
#       Force Wine Staging & DXVK installation
