      # Resolves and installs dependencies into the lib folder. If not already present, generates a shard.lock
      # file from resolved dependencies, locking version numbers or Git commits.
      # Reads and enforces locked versions and commits if a shard.lock file is present. The install command may
      # fail if a locked version doesn't match a requirement, but may succeed if a new dependency was added, as
      # long as it doesn't generate a conflict, thus generating a new shard.lock file.
      #
      # `shards update`
      #
      # Resolves and updates all dependencies into the lib folder again, whatever the locked versions and
      # commits in the shard.lock file. Eventually generates a new shard.lock file.

      # --------------------------------------------------------------------------------
      #
      # running either `shards install` or `shards update` without a `shard.lock` file does the same thing,
      # downloading shards into the `lib` folder and writing a `shard.lock` file
      #
      # if there is a `shard.lock` file `shards install` installs the versions from the lock file while
      # `shards update` does a `shards install` that pretends there isn't a lock file present
