leg 1.0.2

Make your CLIs nicer with minimal effort. Simple wrapper on top of:

• async-std printing macros.
  • Prints to stderr to be nice with your pipes. Except the result function, as expected.
• colored crate:
  • Works on Linux, MacOS, and Windows (Powershell).
  • Respects CLICOLOR/CLICOLOR_FORCE and NO_COLOR behavior.

Do not use this crate in libraries! You should use the log one instead. Visit this section of the book Command line apps in Rust if you want to learn more about this topic.
