Filename Macros
Filename macros are predefined as filenames specified in the dependency (not full filename specifications on disk). These macros do not need to be enclosed in parentheses when invoked; specify only a $ as shown.

|---|---|
$@ |
Current target's full name (path, base name, extension), as currently specified. |
$$@ |
Current target's full name (path, base name, extension), as currently specified. Valid only as a dependent in a dependency. |

Current target's path and base name minus file extension. |
$** |
All dependents of the current target. |
$? |
All dependents with a later timestamp than the current target. |

To specify part of a predefined filename macro, append a macro modifier and enclose the modified macro in parentheses.
