At present your best bet for your first style is to just have the wrapped `proc` receive a `seq[string]` and just test it yourself. Note though, that you aren't really getting much value out of any option parsing framework vs. just using `os.cmdLineParams()`.
While it could be more elegant/automatic, the second thing you ask about works fine with the current `cligen` as shown by `test/MultMultMult.nim` in the `cligen` repo.
