does this need any design work? If someone in the community were to pick it up prior to 0.39 release would it be included?

[alexanderbez]

@marbar3778 not really, and yes please! It should be more or less trivial. Move command instantiation around and remove *cli remainings.

Hi, can I work on this?

Hi, can I work on this?

That would be a great help, 🙏

[alexanderbez]

@dauTT yes pls 🙏 let us know if you need guidance on this, but I think it should be pretty straight forward.

[dauTT]

Is it okay if I follow this convention?

1) single binary name: sim
2) sim client = simcli
3) sim daemon = simd

[aaronc]

@dauTT let's just have all the commands at the top level. So the user would type sim start, sim query, etc.

As for the naming of the binary, I think sim is fine although maybe we choose to adopt one of simd or simcli.

Thanks for looking into this!
