-# -----------
-# - Check for no 'explicit' for multi-arg ctor
-# - Check for boolean assign RHS in parens
-# - Check for ctor initializer-list colon position and spacing
-# - Check that if there's a ctor, there should be a dtor
-# - Check accessors that return non-pointer member variables are
-# declared const
-# - Check accessors that return non-const pointer member vars are
-# *not* declared const
-# - Check for using public includes for testing
-# - Check for spaces between brackets in one-line inline method
-# - Check for no assert()
-# - Check for spaces surrounding operators
-# - Check for 0 in pointer context (should be NULL)
-# - Check for 0 in char context (should be '\0')
-# - Check for camel-case method name conventions for methods
-# that are not simple inline getters and setters
-# - Do not indent namespace contents
-# - Avoid inlining non-trivial constructors in header files
-# - Check for old-school (void) cast for call-sites of functions
-# ignored return value
-# - Check gUnit usage of anonymous namespace

+ Examples:
+ --extensions=hpp,cpp
+

+ The header extensions that cpplint will treat as .h in checks. Values are

+
+ Examples:
+ --headers=hpp,hxx
+ --headers=hpp
+
+ 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
+ root=subdir
+ headers=x,y,...
+
+ "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.
+
+ The "root" option is similar in function to the --root flag (see example
+ above). Paths are relative to the directory of the CPPLINT.cfg.
+
+ The "headers" option is similar in function to the --headers flag
+ (see example above).
+
+ 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
+ file is located) and all sub-directories.
