cata(lyst) for building complex CLI tools.

This crate provides a collection of utilities that make it easier to build CLI tools.

• command: recursively traverse a tree of clap commands and subcommands calling lifecycle hooks at each level.
• [mod@file]: derive clap::value_parser for deserializing values from files. Detects the file format from the extension and currently supports JSON in addition to YAML.
• output: structured output for commands. Users can choose the output format they would like, currently supporting JSON, YAML and pretty.\
• telemetry: a simple way to track activity and errors for your CLI.
