## Description

A Ruby binding for curses, ncurses, and PDCurses.
curses is an extension library for text UI applications.

Formerly part of the Ruby standard library, [curses was removed and placed in this gem][1]
with the release of Ruby 2.1.0. (see [ruby/ruby@9c5b2fd][2])

## Install

    $ gem install curses

## Developers

After checking out the repo, run `bundle install` to install dependencies.

To compile the extension library, run `bundle exec rake compile`.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `curses.gemspec`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
