 To manually cleanup L3D projects, you can always call `l3d delete id1 id2 id3 ...` to remove all related containers of the given projects. Should you want to get such cleanup automatically, when a user leaves L3D, then you just have to set an environment variable `L3D_ALWAYS_CLEANUP=1` on your host before you create the first project.
