Github Source Code
The source code of this project is packaged into a library called Tinker, developed and maintained by Allen Nie. The source code is written in Scala, and requires Scala runtime, and SBT to run. Tinker is still being actively developed at this point, and questions can be asked on github issue page: https://github.com/windweller/Tinker
Terminal-friendly version is now built-in on the library, making it executable on most machines. You can download the latest jar library on GitHub, then try
java -jar Tinker.jar --help on a terminal.
