CraftOS-PC is a fantasy terminal that allows you to write and run
programs inside an '80s-style text console.

CraftOS-PC emulates the popular Minecraft mod "ComputerCraft", which
adds programmable computers to Minecraft using the Lua programming
language. CraftOS-PC takes this experience outside Minecraft to allow
you to run the same programs anywhere you go.

CraftOS-PC provides a set of functions (called APIs) that make it super
easy to do simple tasks such as write text to the screen, read files,
and more. The simplicity of these functions makes CraftOS-PC great for
new programmers, but their power makes it possible to write all sorts of
complex programs with less code.

If you aren't ready to write programs yet, there's already a large
number of programs for ComputerCraft that will work in CraftOS-PC,
ranging from simple games to whole graphical operating systems. These
can be downloaded through the built-in Pastebin and GitHub Gist clients.
