<h1>Running Ant</h1>
<p>Running Ant is simple, when you installed it as described in the previous
section. Just type <code>ant</code>.</p>
<p>When nothing is specified, Ant looks for a <code>build.xml</code>
file in the current directory. If found, it uses that file as the
buildfile. If you use the <code>-find</code> option,
Ant will search for a buildfile in
the parent directory, and so on, until the root of the filesystem
has been reached. To make Ant use
another buildfile, use the command-line

<p> If you've installed Ant as described in the
<a href="install.html"> Installing Ant</a> section,
running Ant from the command-line is simple: just type
<code>ant</code>.</p>
<p>When no arguments are specified, Ant looks for a <code>build.xml</code>
file in the current directory and, if found, uses that file as the
buildfile and runs the "default" target.
If you use the <code>-find</code> option,
Ant will search for a buildfile first in the current directory, then in
the parent directory, and so on, until either a buildfile is found or the root
of the filesystem has been reached. To make Ant use
a buildfile other than <code>build.xml</code>, use the command-line
option <code>-buildfile <i>file</i></code>,
where <i>file</i> is the buildfile you want to use.</p>
where <i>file</i> is the name of the buildfile you want to use.</p>

This can be done with
the <nobr><code>-D<i>property</i>=<i>value</i></code></nobr> option,
where <i>property</i> is the name of the property,
