## ocaml-ledger-wallet
- Library used by `tezos-client` to interact with the Ledger family of hardware
  wallets.
- Cloned from: [ledgerwallet](https://opam.ocaml.org/packages/ledgerwallet/)
  and [ledgerwallet-tezos](https://opam.ocaml.org/packages/ledgerwallet-tezos/)
- Reason for vendoring:
  - It depends on ocaml-hidapi that we currently vendor.
    A library installed by opam cannot depend on a vendored library.
