<span class="command">as</span> can generate a dependency file for the file it creates. This
|
|
file consists of a single rule suitable for <code>make</code> describing the
|
|
dependencies of the main source file.
|
|
|
|
<p>The rule is written to the file named in its argument.
|
|
|
|
<p>This feature is used in the automatic updating of makefiles.
