4# Usage:
5# ./update.sh [PRODUCT]
6#
7# Examples:
8# $ ./update.sh graalvm-ce # will generate ./graalvm-ce/hashes.nix
9# $ ./update.sh # same as above
10# $ ./update.sh graalpy # will generate ./graalpy/hashes.nix
11#
12# Environment variables:
13# FORCE=1 to force the update of a product (e.g.: skip up-to-date checks)
14# VERSION=xx.xx will assume that xx.xx is the new version
