       Examples:

     cpplint.py supports per-directory configurations specified in CPPLINT.cfg
     files. CPPLINT.cfg file can contain a number of key=value pairs.
     Currently the following options are supported:
 
       set noparent
       filter=+filter1,-filter2,...
       exclude_files=regex
+      linelength=80
 
     "set noparent" option prevents cpplint from traversing directory tree
     upwards looking for more .cfg files in parent directories. This option
     is usually placed in the top-level project directory.
 
     The "filter" option is similar in function to --filter flag. It specifies
     message filters in addition to the |_DEFAULT_FILTERS| and those specified
     through --filter command-line flag.
 
     "exclude_files" allows to specify a regular expression to be matched against
     a file name. If the expression matches, the file is skipped and not run
     through liner.
 
+    "linelength" allows to specify the allowed line length for the project.
+
     CPPLINT.cfg has an effect on files in the same directory and all
     sub-directories, unless overridden by a nested configuration file.
 
       Example file:
         filter=-build/include_order,+build/include_alpha
         exclude_files=.*\.cc
 
     The above example disables build/include_order warning and enables
     build/include_alpha as well as excludes all .cc from being
     processed by linter, in the current directory (where the .cfg
