#!/bin/sh
# This install script is intended to download and install the latest available
# release of Wasmer.
# Installer script inspired by:
# 1) https://raw.githubusercontent.com/golang/dep/master/install.sh
# 2) https://sh.rustup.rs
# 3) https://yarnpkg.com/install.sh
# 4) https://raw.githubusercontent.com/brainsik/virtualenv-burrito/master/virtualenv-burrito.sh
#
# It attempts to identify the current platform and an error will be thrown if
# the platform is not supported.
#
# Environment variables:
# - INSTALL_DIRECTORY (optional): defaults to $HOME/.wasmer
# - WASMER_RELEASE_TAG (optional): defaults to fetching the latest release
# - WASMER_OS (optional): use a specific value for OS (mostly for testing)
# - WASMER_ARCH (optional): use a specific value for ARCH (mostly for testing)
#
# You can install using this script:
# $ curl https://raw.githubusercontent.com/wasmerio/wasmer/master/install.sh | sh
