Examples:
--extensions=%s

includeorder=default|standardcfirst
For the build/include_order rule, the default is to blindly assume angle
bracket includes with file extension are c-system-headers (default),
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
treat all others as separate group of "other system headers". The C headers
included are those of the C-standard lib and closely related ones.

headers=x,y,...
The header extensions that cpplint will treat as .h in checks. Values are
automatically added to --extensions list.
