to uniquely identify the package. It can be requested in the same way as an

application's third UID, through https://www.symbiansigned.com or for convenience

it can use the same value as the application's third UID </p> </li>

<li id="GUID-A04BA1AD-6933-5F4B-A405-6F0D8E9862FB"><p>By default, the contents

of SIS files are compressed. This can be prevented by using the <codeph>NOCOMPRESS</codeph> option

in the PKG header. Specifying <codeph>NOCOMPRESS</codeph> is not recommended

unless you are installing files that are already compressed, for example JPEGs. </p> </li>
