# This script is not robust for all platforms or situations. Use as a rough
#  example, but invest effort in what it's trying to do, and what it produces.
#  (make sure you don't build in features you don't need, etc).

# To install the installer silently you may run it like this:
# ./megaglest-installer.run --noprompt --i-agree-to-all-licenses --destination /home/softcoder/megaglest-temp-test --noreadme --ui=stdio

# Consider setting this for small packages if there's plenty of RAM and CPU available:
#export XZ_OPT="$XZ_OPT -9e"
