Synopsis Synopsis
-------- --------
Most programs that provide a command-line interface use a special-purpose library to make the process easier, such as the GNU Project's `getopt` library. The Rust team provides their own alternative, `getoptions`, which deserves an award for the Most Originally Named Project Ever.

In all seriousness, `getoptions` is a fantastic library that gives the developers all of the power necessary to create and interface with command-line arguments. However, with all that power comes complexity. `getoptions` -- while straight forward to use -- is verbose. The developer has to call different functions repeatedly in order to add different command-line options to their programs. While the only victim here is the developer's wrists due to carpal tunnel, I felt that there was a In all seriousness, `getopts` is a fantastic library that gives the developers all of the power necessary to create and interface with command-line arguments.
