#   and the pipeline runs this, then the version will be 1.2.3
#   and this is run locally, then the version will be 1.2.3
#   and this is run locally with committed changes, then the version will be 1.2.3-{commits}-{git hash}
#   and this is run locally with uncommitted changes, then the version will be appended with '-dirty'
