Usually contained in autoload.map.php, itself within shared.phar, the map is a simple array structure.

• It contains one ["class"] list.
• A ["function"] list.
• And prepares ["const"] entries as well.
• For single-dir based maps it also contains a directory fingerprint in ["fp"].

Each list associates:

• an identifier (possibly with namespace prefixes)
• with the filename of its declaration.
