#
# Git snapshot build script. Checks latest Git commit against Supermodel3.com
# download page and builds and uploads a snapshot if needed. Intended to be run
# at least once daily as part of an automated job.
#
# Dependencies:
# - MSYS2 installed at c:\msys64
# - mingw64/mingw-w64-x86_64-gcc package
# - mingw64/mingw-w64-x86_64-make package
# - mingw64/mingw-w64-x86_64-SDL2 package
# - mingw64/mingw-w64-x86_64-SDL2_net package
# - msys/subversion package
# - msys/zip package
# - git
# - paramiko (Python package for SSH/SFTP)
#
# To perform a test run:
# - Download https://supermodel3.com/Download.html to the directory from
# which the script will be run.
# - Run: python supermodel_build_bot.py --working-dir=c:\tmp\build --test-run
