### 2.5 `.include` Search Path: `-I` path

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