Build file used by Sublime Text, an open source text editor used primarily to edit source code; contains a build system, which includes JSON formatted configuration data, a Sublime Text command that drives the process, and an optional, external executable file.

A build system is designed to run an external program to process your Sublime Text project files and see the generated output without having to leave the Sublime Text application. It is helpful for when you need to run files through build programs, interpreters, and command line utilities. NOTE: Build options can be accessed through the Tools menu in Sublime Text.
