    # How the tag and release targets work
    #
    # Each time a build is run on the main branch the CHANGELOG.md file is
    # checked To see if there is a new version tag with details under it.  If a
    # version with details is found then **tag** creates a new tag with the
    # proper version.
    #
    # The creation of the tag branch triggers the **release** stage.
    #
    # The release stage builds tar.gz and zip artificts as well as creates a
    # SHA256 checksum of the files.  The process then pushes these files up to
    # Github for hosting.
    #
    # Why do this?  Yocto and other build systems depend on the artifacts being
    # consistent each time they are downloaded, but there is an issue with the
    # way Github generates the artifacts on the fly where on occasion the
    # checksum changes.  By explicitly producing our own artifacts we eliminate
    # this issue for systems that rely on the checksum being constant
