Thie CAR format used for repository exports is compatible with IPLD. This means
the generic `ipfs` command-line tool (aka,
[kubo](https://docs.ipfs.tech/reference/kubo/cli/#ipfs-dag)) can be used to
import and explore the tree contents.
NOTE: The nested '/' on CID references in the `ipfs dag get` output below seems
to be a representation of the CBOR "tag" for CID types. There is not actually a
nested map/object with a key "/". This is confirmed by inspecting the raw CBOR
using a python CBOR library (later on below).
$ ipfs dag import example_repo.car

$ ipfs dag get bafyreicaxix5adqs6e2yjmp4hui2ugfrn2ahquzrcdzb4b6j5l4xskansa

Can also fetch raw MST nodes and records:
# app.bsky.post/3jg4f3m6xas2a record
$ ipfs block stat bafyreicaxix5adqs6e2yjmp4hui2ugfrn2ahquzrcdzb4b6j5l4xskansa

$ ipfs block get bafyreicaxix5adqs6e2yjmp4hui2ugfrn2ahquzrcdzb4b6j5l4xskansa > post.cbor
# MST node
$ ipfs block get bafyreidrm6a2yucvumvug253af5fuxxwatgzid2wlq5c23kn5fvztwlbxi > mst_node.cbor
Load CBOR records in python (`python3-cbor`):
import cbor
cbor.load(open("./post.cbor", "rb"))
# {'text': 'blah'}
cbor.load(open("./mst_node.cbor", "rb"))
#{'e': [{'k': 'app.bsky.follow/3jg4dmbn5y22a',
