<section><title>What is it?</title>
<p>The POI project is the master project for developing pure
Java ports of file formats based on Microsoft's OLE 2 Compound
Document Format. OLE 2 Compound Document Format is used by
Microsoft Office Documents, as well as by programs using MFC
property sets to serialize their document objects.
</p>
</section>
<section><title>Sub-Projects</title>
<p>
There following are ports, packages or components contained in the POI project.
</p>
<section><title>POIFS</title>

<link href="poifs/index.html">POIFS</link> is the set of APIs
for reading and writing OLE 2 Compound Document Formats using (only) Java.

</p>
</section>
<section><title>POI-Utils</title>
<p>
<link href="utils/index.html">POI-Utils</link> are general purpose artifacts
from POI development that have not yet been implemented elsewhere. We're
always looking to donate these and maintain them as part of a general library
used in another project. These are things we need to complete our mission but
are generally outside of it.
</p>
</section>
</section>
<section>
<title>Examples</title>
<p>Small sample programs using the POI API are available in the
<em>src/examples</em> directory of the source distribution. Before
studying the source code you might want to have a look at the
"Examples" section of the <link
href="apidocs/overview-summary.html">POI API
documentation</link>.</p>
</section>
<section><title>Contributed Software</title>
<p>Besides the "official" components outlined above there is some further
software distributed with POI. This is called "contributed" software. It
is not explicitly recommended or even maintained by the POI team, but
it might still be useful to you.</p>
<section>
<title>POI Browser</title>
<p>The POI Browser is a very simple Swing GUI tool that displays the
internal structure of a Microsoft Office file and especially the
property set streams. Further information and instructions how to
execute it can be found in the <link
href="apidocs/org/apache/poi/contrib/poibrowser/package-summary.html#package_description">POI
Browser package description</link>.</p>
