 ##### Note
+
 Failing to follow this results in difficult to diagnose errors due to picking up the wrong file by incorrectly specifying the scope when it is included. For example, in a typical case where the `#include ""` search algorithm may search for a file existing at a local relative path first, then using this form to refer to a file that is not locally relative could mean that if a file ever comes into existence at the local relative path (e.g. the including file is moved to a new location), it will now be found ahead of the previous include file and the set of includes will have been changed in an unexpected way.
 
 Library creators should put their headers in a folder and have clients include those files using the relative path `#include <some_library/common.h>`
