Cpplint is a command-line tool to check C/C++ files for style issues following `Google's C++ style guide <http://google.github.io/styleguide/cppguide.html>`_.

Cpplint is developed and maintained by Google Inc. at `google/styleguide <https://github.com/google/styleguide>`_, also see see the `wikipedia entry <http://en.wikipedia.org/wiki/Cpplint>`_

While Google maintains cpplint, Google is not (very) responsive to issues and pull requests, this fork aims to be (somewhat) more open to add fixes to cpplint to enable fixes, when those fixes make cpplint usable in wider contexts.

For the build/include_order rule, the default is to blindly assume angle

even knowing this will have false classifications.

The default is established at google.

standardcfirst means to instead use an allow-list of known c headers and

included are those of the C-standard lib and closely related ones.
