This is an attempt to implement the well-known app curl, as a drop-in replacement. It's an exercise to learn more Go and programming patterns.
It's implemented as a module, so it can be imported by other projects, and it has a command line tool that uses the module that can be installed as a binary on any system that go can compile to.
In the spirit of the official http package, this module implements a Request type
that can be used to make requests.
