			 <p><b>Capabilities</b> - Click the Choose... button to select Capabilities. A capability is an access token that corresponds to permission to access sensitive system resources. Platform security permits access to sensitive APIs according to capabilities. Capabilities are used to specify what functionality an application is trusted to use; they are allocated to the application at build time and are policed at run time. Once the capabilities are assigned to the application, they cannot be changed. Thus an application has a set of unalterable capabilities that describe what access the application has to the APIs.</p>

			 <p>There are three suggested ways to establish which capabilities an application requires.</p>

			   <li>The first method is initially to allocate capabilities based on the general operations that the application performs. For example, an instant messaging application would probably require NetworkServices to access the Internet and ReadUserData to read the user&rsquo;s contacts.</li>

			   <li>The second method is to use the Symbian Developer Library, which lists the capabilities required by each API. Note that some APIs may be marked as &ldquo;Dependent&rdquo;, meaning that the need for the capability depends on the parameters being passed. For example, accessing a file in an application&rsquo;s private data area requires no capabilities, but accessing a file in \sys\bin requires the <span class="code">AllFiles</span> capability.</li>

			   <li>The third method is to run the application in the emulator, analyzing the debug file (in the system temporary directory) for capability violations. The output will state the API that caused the violation and what capability was expected.</li>

			 <p><b>Secure ID</b> - Enter the Secure ID. The SID is used to determine which private directory a process can access. It is also used to identify the caller applications. An application's SID is defined within its .mmp file, and is used to uniquely identify the application. SID values are requested from the Symbian Signed Web site (www.symbiansigned.com).  The Software Installer (SWI) is responsible for ensuring that SIDs are locally unique, i.e., that no two applications have the same SID value on a particular target device.</p>

			 <p><b>Disable optimizations in debug builds</b> - Check this option to disable optimizations when building a debug version of your application. Since optimization changes the code created by the compiler, it is best to optimize your code after you have fully tested and debugged it. If a program works in a debug build, but fails in a release build, it is likely that one of the compiler optimizations is exposing a defect in your source code. To isolate the problem, you should disable selected optimizations for each source code file, until you locate the file and the optimization that is causing the problem.</p></td>
