Package: ruby-tty-which
Description: platform-independent implementation of Unix which command
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.
