Summary
In this chapter, we started to build our very own CLI application, Bookmarkr, which is a bookmark manager provided as a CLI application, so it can be used within a Terminal window.
We started with a console application (because remember, “At the core of every CLI application is a console application”), and then we introduced a library for parsing its command-line arguments including commands, subcommands, and options so we don’t need to reinvent the wheel.
In the upcoming chapter, we will see how to control inputs and outputs and how to read data from and write data to a file so we can perform backup and restore operations for our bookmarks. This will prove especially useful to import and export bookmarks into and out of our bookmark manager application
