 `vim-cpplint` is a Vim plugin that runs the currently open file through
 cpplint.py, a static syntax and style checker for C++ source code.

     autocmd FileType cpp map <buffer> <F3> :call Cpplint()<CR>
 
 
+By default the plugin support following file extensions: 
+*.cc, *.h, *.cpp, *.cu, *.cuh
+
+You can change it by setting in .vimrc the variable: 
+
+    let g:cpplint_extensions = "cpp,hpp,h,c,cc,cu,cuh"

+The line length, by default it is 80 characters but you can change it by

 Tips
 ----
 A tip might be to run the cpplint.py check every time you write a C++ file, to
 enable this, add the following line to your `.vimrc` file (thanks
 [Godefroid](http://github.com/gotcha)!):
 
     autocmd BufWritePost *.h,*.cpp call Cpplint()
+
+False positives can be ignored by putting 
+
+    // NOLINT at the end of the line or 
+    // NOLINTNEXTLINE in the previous line.
