<p>There is always one object file output when you run <code>as</code>. By
default it has the name
<samp>a.out</samp> (or <samp>b.out</samp>, for Intel 960 targets only).
You use this option (which takes exactly one filename) to give the
object file a different name.
</p>
<p>Whatever the object file is called, <code>as</code> overwrites any
existing file of the same name.
