create-julia-artifacts-toml

#!/bin/bash

# Creates Julia’s Artifacts.toml for preprocessor binaries.
# Used by the Gitlab CI file of the preprocessor.
#
# Must be given a git commit SHA as first argument, and a base download URL
# as second argument.
#
# In the current directory, there must be a directory whose name is the SHA.
# This directory must itself contain several directories corresponding to platforms
# ("linux-i686", "windows-x86_64"…). Each of these directories must contain a
# dynare-preprocessor.tar.gz file.
#
# The Julia executable must be in the path.
#
# The Artifacts.toml file is created in directory named after the git commit SHA.
