+is a wrapper around the MakeSIS, SignSIS, and MakeKeys tools, which automates
+the process of generating and signing SIS files. It supports creating new
+SIS files from package (PKG) files, signing existing package files and generating
+private-public key pair and certificate requests for signing. </p> </li>

+<dt>PKG File</dt>
+<dd><p>A package (PKG) file contains information required by the SIS file
+creation tools to create a SIS file. </p> </dd>
+</dlentry>
+<dlentry>
+<dt>SIS File</dt>
+<dd><p>A Symbian Installation Source (SIS) file is a collection of executables
+and data files, packaged in a way that the software installer can install
+them onto a device. SIS files can be preinstalled on a device. </p> </dd>
+</dlentry>
+<dlentry>
+<dt>Signing</dt>
+<dd><p>A SIS file must be signed with a digital signature, which is used in
+verifying the identity of the vendor of an installation file. This ensures
+that the file has not been tampered with since it was signed. For details
+see, <xref href="GUID-AFBD4ED6-9588-531C-8EDF-566DB1D03088.dita">Signing</xref>. </p> </dd>
+</dlentry>
+<dlentry>
+<dt>Eclipsing</dt>
+<dd><p>Eclipsing is a mechanism to upgrade files existing on the ROM drive,
+by installing a new version of the same on the RAM drive. For details see, <xref href="GUID-F8A26275-883A-5299-9C37-9DDCC2F62108.dita">Eclipsing</xref>. </p> </dd>

+the following: </p> <ul>
+<li id="GUID-0E5E3BED-B678-54E1-98F0-09672A5BDA8C"><p> <b>Create and sign
+an installation file</b>  </p> <p>Symbian application developers can create
+installation packages using <codeph>MakeSIS</codeph> and sign them using <codeph>SignSIS</codeph>.
+Alternatively, the <codeph>CreateSIS</codeph> tool, which is a wrapper around <codeph>MakeSIS</codeph> and <codeph>SignSIS</codeph>,
+can be used to create and sign an installation file. For details see <xref href="GUID-03BBEA31-3266-5B1C-9017-4EE7EA4AF1A8.dita">Creating and Signing an Installation
+File</xref>  </p> </li>
+<li id="GUID-E5CAFFB6-7396-5220-942D-2406C39D8E01"><p> <b>Upgrade OS components</b>  </p> <p>The
+software installer enables a device manufacturer to replace binaries and data
+files in ROM, for example, to fix a software issue, by means of eclipsing.
+For details, see <xref href="GUID-7F65B69A-6AC1-509C-91E8-9E49ED0BFEC0.dita">Upgrading
