For building Wine

wine_build.sh

#!/bin/bash

# Builds Wine

# Notes:
# 1. Targeted for usage inside a VM (use shared directory $HOME/mnt/vmshare between host and guest).
# 2. You'd need to separately push the result on the host to whatever location you want (like to /opt).
# 3. Place any manual patches in ${HOME}/build/patches
# 4  You can override the Wine repo. For example, to build Wine-wayland:
#
#    wine_repo='https://gitlab.collabora.com/alf/wine.git' wine_branch='wayland' wine_build.sh
#
# 5. Override arch to something else if you aren't using Ryzen.
