above - auto "use lib" when a module is in the tree of the PWD
use above "My::Module";
Used by the command-line wrappers for Command modules which are developer tools.
Do NOT use this in modules, or user applications.
Uses a module as though the cwd and each of its parent directories were at the beginnig of @INC. If found in that path, the parent directory is kept as though by "use lib".
