Overview

A BUILD is a short program, an interpretable list of Starlark statements. It can be named BUILD or BUILD.bazel and where both exist, BUILD.bazel takes precedence.

General Syntax

Variables must be defined before they are used.

The relative order in which build rules are declared is unimportant.

Build Rules

When a build rule function is executed, it creates a new target in the graph, which can later referred using a label.
