Sure, thanks for noticing that they're missing.  Based on the docs, my
understanding is that "envmodules" can only be used within a rule:

    rule bwa:
        envmodules:
            "bio/bwa/0.7.9"
        [...]

On the other hand, it looks like "container" can be used either within a
rule or at the top-level.  Is that correct?

Hmm, not sure.  Starting a separate thread with a minimal reproducer
would be great.  Thanks.

Subject: [PATCH] mode: Add "container" and "envmodules" keywords

Register "container" as both a field key and a top-level command
because an example of both is present in the Snakemake docs.
