First of all: congratulations for the new site and forum. I have been following Redox for a while. It is great to see this awesome project growing.
Just as way to learn Rust I have built a few command line tools mimicking existing tools. Redox source was a very nice for inspiration and comparison purpose. I think this is great entry point for people that want to collaborate as they are rather isolated. How about making a list of missing/desired command line tools so people can contribute?
Also related to this, I built a small git clone implementing 4 of the plumbing commands.
clap was very useful to make it work. However, it seems that Redox as well as other established projects are just using vainilla rust for this. Is there any particular reason?
