1 =====================================
1 
1 Use this option to add a PATH to the list of directories 'as' searches
11 for files specified in '.include' directives (⇒(as))).  You may use '-I' as many times as necessary to include a
1 variety of paths.  The current working directory is always searched
1 first; after that, 'as' searches any '-I' directories in the same order
1 as they were specified (left to right) on the command line.
