It is sometimes difficult to work out what object a PHID is referring to. For me, it usually involves querying the database. It would be useful if there was a `./bin/lookup` script which could be used to query objects based on their PHID (or some other identifier).
An example of how I imagine this would be used:
```
> ./bin/lookup PHID-REPO-ffrhepqxcgyorisvabky
Repository rX
> ./bin/lookup PHID-CMIT-sr6zv7bzzfyql4vfn6cv
Commit rXcfb048ca2d5fab185f56b316c86f792b1a4ce08d.
```
