BuildXL

microsoft/BuildXL/.github/copilot-instructions.md

BuildXL is a distributed, cached, incremental build engine. Frontends construct a pip graph, then the scheduler executes it.

Important concepts: - A pip is a node in the build DAG, such as a process, copy, write, service, or IPC operation. - Frontends include DScript, MSBuild, JavaScript, Ninja, NuGet, and Download. - Qualifiers parameterize builds, commonly by configuration and platform.…
