# Before building this package:
# Download the Windows installer for the game off of GOG.com and put it in the
# same folder as this PKGBUILD.  Upstream recommends using the English version
# but other languages should work fine as well.  Rename the installer to
# "setup_albion.exe" (without the quotes).
