# Refuse to build in hostile package environments. The code and build script licenses do not allow for
# packages, and I'm sick of dealing with people complaining about things broken by packagers, and then
# being attacked by package maintainers who violate their distribution's codes of conduct. Attempts to
# request removal of these packages have been unsuccessful, so we have to resort to this.
# NOTE: You do NOT have permission to distribute build scripts or patches that modify the build system
# without explicit permission from the copyright holder.
# DuckStation's code is public so it can be audited and learned from. Not to repackage.
# This is why we can't have nice things.
