When I run:

`Pkg.add(url="git@github.com:sylvaticus/DICE.jl.git", rev="master")`

(without Pkg.dev)

where the source code of the package is saved ?

Let’s try it out, with a simpler package.

```julia
$ mkdir /tmp/testdepot
$ JULIA_DEPOT_PATH=/tmp/testdepot julia

```

It’s maybe not completely obvious but I interpret this to be that we have a clone of the Example repository in `clones` and a snapshot of the master branch in `packages`. When you don’t set `JULIA_DEPOT_PATH` those would be inside your `.julia` directory.

The subdirectory name `A1z7K` is computed from some information that I don’t remember in detail but you can find it for the loaded version of the package with `pathof`. I have never looked into the naming of the subdirectories of `clones`.

It is a [CRC32 hash of the uuid and the tree sha1 hash](https://github.com/JuliaLang/julia/blob/fe2617378cb6ea56a1b5e41ff33b7ad34bfa71ac/base/loading.jl#L202-L206).
