Comparison to other cleanup tools, tagging your crate with keywords

[matu3ba]

As I checked crates.io I searched for the keywords cleanup free clean (for which your crate sadly is not tagged) and found:

1. https://github.com/whitfin/detox
2. https://github.com/woubuc/sweep

For example I liked about detox that it checks what was lately used.
The optimum would be to also show the latest building time attached to the projects, but that would require some shell setup.
