<section id="GUID-5917F986-4386-401E-A8F2-4BE111C1A48F"> <p>This guide is
adapted from material originally intended to accompany source code for sample
front end processors (FEPs) TFEP1Plugin (a keyboard-based FEP) and TFEP2Plugin
(a mouse/pen-based FEP). </p> <p>TFEP1Plugin and TFEP2Plugin are available
to Symbian DevKit licensees and may be found in the Symbian platform source
in the <filepath>app-framework\feptest\</filepath> directory. </p> <p>SDK
licensees do not have access to the source but must find sufficient information
within the guide. </p> <p><b>Note:</b> Platform security that was introduced
in Symbian OS v9.1, brought some changes to the way FEPs are created and loaded. <i>Prospective
FEP developers must note that FEPs now require a capability of All-Tcb and
must therefore ensure that they are able to achieve this before commencing.</i> </p> <p>The
guide is divided into the following sections: </p> <p><xref href="GUID-6CEAFE12-EB30-5231-94F4-2D097E79BFE0.dita">Implementing
