# This script will generate a release on github/lfs-test-server.
# Ensure that you've bumped version in main.go, then run the script.
# The script does the following
#   * Ensure the build succeeds (and pulls the version from the build)
#   * Ensure the tests pass
#   * Cross compiles for supported platforms
#   * Creates the release on github/lfs-test-server
#   * Uploads binary assets to the release.
