# Stack installation script.
#
# This script is meant for quick & easy install via:
# 'curl -sSL https://get.haskellstack.org/ | sh'
# or:
# 'wget -qO- https://get.haskellstack.org/ | sh'
#
# By default, this installs 'stack' to '/usr/local/bin'.
#
# Arguments (use `... | sh -s - ARGUMENTS`)
#
# -q: reduce script's output
# -f: force over-write even if 'stack' already installed
# -d DESTDIR: change destination directory
#
# Make pull requests at:
# https://github.com/commercialhaskell/stack/blob/master/etc/scripts/get-stack.sh
