#!/bin/sh

# This install script is intended to download and install the latest available
# release of the winapps rewrite..
#
# It attempts to identify the current platform and an error will be thrown if
# the platform is not supported.
# It is based on the install script from dep (https://raw.githubusercontent.com/golang/dep/master/install.sh)
#
# Environment variables:
# - INSTALL_DIRECTORY (optional): defaults to ~/.local/bin
# - WINAPPS_RELEASE_TAG (optional): defaults to fetching the latest release
# - WINAPPS_USE_MUSL (optional): use musl instead of glibc
# - WINAPPS_ARCH (optional): use a specific value for ARCH (mostly for testing)
#
# You can install using this script:
# $ curl https://raw.githubusercontent.com/winapps-org-winapps/rewrite/scripts/install.sh | sh
