This directory contains build system files related to the Bazel build system. https://bazel.build/

Files named *.BUILD are Drake-specific build rules for external libraries or tools that do not natively support Bazel. https://bazel.build/versions/master/docs/external.html#depending-on-non-bazel-projects

Files named *.bzl are Skylark extensions. https://bazel.build/versions/master/docs/skylark/concepts.html

drake.cps is the Common Package Specification for Drake, that provides the necessary information for Drake to be consumed by other projects. Right now it is hand edited; the list of includes should match the list of folders in package_drake.sh's include/external folder. This is also used to generate drake-config.cmake via cps2cmake. https://mwoehlke.github.io/cps/ https://github.com/mwoehlke/pycps/

See drake/doc/bazel.rst for additional Drake-specific information.
