# Install the latest release of the SynQt command line tool.
#
# This script is what get.synqt.org serves: it is published at both the root
# and the /install.sh path (get.synqt.org's index.html is a byte for byte copy
# of this file), so either of these installs SynQt:
#
#   curl -fsSL https://get.synqt.org | sh
#   curl -fsSL https://get.synqt.org/install.sh | sh
#
# This downloads the asset for your operating system and architecture from the
# latest non prerelease on GitHub. The /releases/latest/download/<asset> path
# always resolves to the newest stable release, so this script self updates.
#
# Reading a script before piping it to a shell is strongly recommended. This one
# only downloads, extracts, and copies a single binary into a bin directory.
