		Poliqarp 1.3 lifts limitations on corpora sizes: it should be possible to build and process any reasonable
		corpus up to 2G segments. Unfortunately, the binary corpus format needed to be changed.
	</p><p>
		You can check version of your corpus by inspecting the
		<code class="filename"><em class="replaceable"><code>*</code></em>.cdf</code> file:
		</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
					lack of the <code class="filename"><em class="replaceable"><code>*</code></em>.cdf</code>
					indicates the old format;
				</p></li><li class="listitem"><p><code class="literal">version = 1</code> string indicates the old format;</p></li><li class="listitem"><p><code class="literal">version = 2</code> string indicates the new one.</p></li></ul></div><p>
	</p><p>
		Sakura, the underlying library, does no longer support the old format. However, bpupgrade, the conversion utility is
		provided.
	</p></div><div class="refsection" title="Description"><a id="idp3455312"></a><h2>Description</h2><p>
		bpupgrade converts a legacy (version 1) binary Poliqarp corpus to the new format (version 2).
