<context id="GUID-B81294BB-5145-48B0-B39D-D69C9186ED2C">       <p>Project file defines the location of the source
files that required are to build a plug-in.</p><p>To write a converter
DLL project file, specify the following in the <codeph>.mmp</codeph> file:</p><ul>
<li><p>The extension of the target file as <codeph>.dll</codeph>.</p></li>
<li><p>The <codeph>TARGETTYPE</codeph> as <codeph>plugin</codeph>.</p></li>
<li><p>The second UID as <codeph>0x10009d8d</codeph>. This value identifies
the DLL as an ECom plug-in. The third UID (<codeph>0xE800009B</codeph> in this example) must be unique and properly allocated. See the <xref href="https://www.symbiansigned.com/app/page" scope="external">Symbian
Signed</xref> Symbian Signed web site for information on how to allocate
UIDs.</p></li>
<li><p>The library section must include <codeph>conarc.lib</codeph>. </p></li>
