After the download has finished, extract the file to a location of your choice. We can use the unpacker that is included in Mac OS X by default, but any third-party unpacker should work as well. Let's take a look at the following screenshot to see what the Sparrow package has to offer:
BUILDING.md: This gives a quick start on how to use the library
CHANGELOG.md: This gives a detailed list of items on what exactly changed between the versions
LICENSE.md: This is the license Sparrow uses
README.md: This is a short introduction into what Sparrow is
Like many other pieces of software in the Mac/iOS universe, Sparrow is licensed under an unmodified two-clause Simplified BSD license, which allows us to use Sparrow as long as the copyright notice, the list of conditions, and the disclaimer is distributed with the source or the application.
What does this mean if we were to modify the source code?
The modified source code must have the same
LICENSE.md file and the contents of this file are not allowed to change.
What does this mean if we were to develop a game with Sparrow and distribute the game on the Apple App Store?
