ruby-tty-which - 0.5.0-1 main

This library provides a platform-independent analogue of Unix `which`
command.
.
TTY::Which has a `which` method that searches set of directories for an
executable file based on the `PATH` environment variable, which returns
an absolute path if the executable program exists, and `nil` otherwise.
.
This is part of the TTY components framework to easily build terminal
applications in Ruby.
