The documentation of the snakemake CLI (https://snakemake.readthedocs.io/en/stable/executing/cli.html) seems to convert the two dashes in the beginning of an option into an n-dash in the text description of the options. For instance, --rerun-triggers becomes –rerun-trigger (incidentally, this is also missing an s at the end). This makes it impossible to copy-paste options from the text description, which is however useful for examples from there.
