# Wasmer build tool
#
# This is a script to build Wasmer in a Docker sandbox.
#
# To use the script, first make sure Docker is installed. Then build the
# sandbox image with:
#
#   docker build --file Dockerfile.build --tag wasmer-build .
#
# After the sandbox image is built successfully, you can run commands in it
# with this script.
#
# For example, to build Wasmer, run:
#
#   ./build make
#
# To test Wasmer, run:
#
#   ./build make test
#
# and so on.
