Overview

Terminal features auto-detection.

Involved in a terminal are the terminal emulator in use (Tput::Emulator) and the term type initialized/running in it (ENV["TERM"] usually).

After those two variables are known, the features autodetection is ran to figure out the final details of terminal's behavior.
