Using the wonderful tool "jaq" to perform "jq-like" operatoins in a Cargo.lock file

do youself a solid and replace jq with jaq

WHY?

Because jaq functions the same as jq while supporting the same feature set for yaml, toml and many other serialization formats which makes it awesome.

And because jaq's author is a badass computer scientist.

It starts with Monte-carlo binary trees depicted as willow trees representing adversarial artificial neural networks where each neural net is a tree. There are three trees, owned by the companies: Google, Amazon and Apple (respectively). The trees emit shimmering photons against each other where such lights represent information being transfered between trees. From there until the end, the three trees fight each other with attacks where information is both the attack and the defence.
