file format</b> </p> <p>Apart from the options listed above, you can use the <filepath>epocrc.config</filepath> file

located at <filepath>epoc32\tools\</filepath> to configure the pre-processor

and the <codeph>rcomp</codeph> tool. The file is supplied to each Symbian

platform licensee as they need it, but it may not be present on some platforms. </p> <p>The <filepath>epocrc.config</filepath> file

contains the following options: </p> <ul>

<li id="GUID-0E0AE904-D462-5780-898E-95E04AA5884D"><p> <codeph>check_rls_items</codeph>:

This option can either be set to 0 or 1. If you want to check for the presence

of localisation comment tags before each RLS item declaration, set it to 1,

otherwise set it to 0. If there are no localisation comment tags within the

resource file, it is assumed that localisation is not required for this file. </p> </li>

<li id="GUID-ABEB6B58-5C5A-5D21-A74C-7B4DFFD1EBC9"><p> <codeph>strict_checking</codeph>:

This option can either be set to 0 or 1. If you set it to 1, the <codeph>rcomp</codeph> tool

warns you if the <filepath>rpp</filepath> file contains RLS item declarations

without the localisation comment tags. If you want to enable this functionality,

you must set <codeph>check_rls_items</codeph> to 1. </p> </li>

<li id="GUID-5F0CD403-B332-594A-AAF0-7D7BE11882C1"><p> <codeph>include:</codeph>:

This option is used to specify files and directories, which need to be passed

to the C++ pre-processor. File names and directory names must be relative

to <codeph>EPOCROOT</codeph>. </p> </li>

</ul><note>  You can comment a line in the <filepath>epocrc.config</filepath> file

by preceding it by '#'. </note> <p>Here is an example of the <filepath>epocrc.config</filepath> file,

which enables the <codeph>strict_checking</codeph> and <codeph>check_rls_items</codeph> options,

and lists the resource headers to be included using the <codeph>include:</codeph> option: </p> <codeblock id="GUID-F02F6D20-6370-5092-A1B8-D4EA475ECAE4" xml:space="preserve"># epocrc.config
