(incubating) is done through the command line interface. It follows the form
 at of:</p><p><code>pio &lt;command&gt; [options] 
&lt;args&gt;...</code></p><p>You can run <code>pio help</code> to see a list of 
all available commands and <code>pio help &lt;command&gt;</code> to see details 
of the command.</p><p>Apache PredictionIO (incubating) commands can be 
separated into the following three categories.</p><h2 id='general-commands' 
class='header-anchors'>General Commands</h2><p><code>pio help</code> Display 
usage summary. <code>pio help &lt;command&gt;</code> to read about a specific 
subcommand.</p><p><code>pio version</code> Displays the version of the 
installed PredictionIO.</p><p><code>pio status</code> Displays install path and 
running status of PredictionIO system and its dependencies.</p><h2 
id='event-server-commands' class='header-anchors'>Event Server 
Commands</h2><p><code>pio eventserver</code> Launch the Event 
Server.</p><p><code>pio app</code> Manage apps that are used by the Event 
Server.</p><p><code>pio app data-delete &lt;name&gt;</code> deletes a

&lt;name&gt;</code> deletes the app and its data.</p><p> <code>--ip 
&lt;value&gt;</code> IP to bind to. Default to localhost.</p><p> <code>--port 
&lt;value&gt;</code> Port to bind to. Default to 7070.</p><p><code>pio 
accesskey</code> Manage app access keys.</p><h2 id='engine-commands' 
class='header-anchors'>Engine Commands</h2><p>Engine commands need to be run 
from the directory that contains the engine project. <code>--debug</code> and 
<code>--verbose</code> flags will provide debug and third-party informational 
messages.</p><p><code>pio build</code> Build the engine at the current 
directory.</p><p><code>pio train</code> Kick off a training using an 
engine.</p><p><code>pio deploy</code> Deploy an engine as an engine 
server.</p><p><code>pio batchpredict</code> Process bulk predictions using an 
engine.</p><p>For <code>deploy</code> &amp; <code>batchpredict</code>, if 
<code>--engine-instance-id</code> is not specified, it wil
 l use the latest trained instance.</p></div></div></div></div><footer><div

PredictionIO is an effort undergoing incubation at The Apache Sof
 tware Foundation (ASF), sponsored by the Apache Incubator. Incubation is 
required of all newly accepted projects until a further review indicates that 
the infrastructure, communications, and decision making process have stabilized 
in a manner consistent with other successful ASF projects. While incubation 
status is not necessarily a reflection of the completeness or stability of the 
code, it does indicate that the project has yet to be fully endorsed by the 
ASF.</span></div></div></div><div id="footer-bottom"><div

commands and <code>pio help &lt;command&gt;</code> to see details of the 
command.</p><p>Apache PredictionIO commands can be separated into the following 
three categories.</p><h2 id='general-commands' class='header-anchors'>General 
Commands</h2><p><code>pio help</code> Display usage summary. <code>pio help 
&lt;command&gt;</code> to read about a specific subcommand.</p><p><code>pio
