"CliFx is a simple-to-use, yet powerful framework for building command-line applications. Its primary goal is to completely take over the user input layer, letting you forget about the infrastructure and instead focus on writing your application. This framework uses a declarative class-first approach for defining commands, avoiding excessive boilerplate code and complex configurations. An important property of CliFx, when compared to some other libraries, is that it's not just a parser -- it's a complete application framework. The main goal of the library is to provide a consistent and enjoyable development experience when building command-line applications. At its core, CliFx is highly opinionated, giving preference to convention over configuration, strictness over extensibility, consistency over ambiguity, and so on."
