Bug 1132771 - Add Files to moz.build with ability to define Bugzilla component The Files sub-context allows us to attach metadata to files based on pattern matching rules. Patterns are matched against files in a last-write-wins fashion. The sub-context defines the BUG_COMPONENT variable, which is a 2-tuple (actually a named tuple) defining the Bugzilla product and component for files. There are no consumers yet. But an eventual use case will be to suggest a bug component for a patch/commit. Another will be to automatically suggest a bug component for a failing test.
