+to use the post-linker (elf2e32)</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The post-linker is a Symbian-specific build tool. Its principal function
+is to create executables (DLLs and EXEs) in the particular format required
+by Symbian platform, known as the <i>E32Image</i> format. Commercial compiler
+and linkers, such as ARM's RVCT and GNU GCC, cannot directly generate that
+format. Such compilers do however support a standard output format called
+the Executable and Linking Format (ELF) (defined at <xref href="http://www.caldera.com/developers/gabi/" scope="external">http://www.caldera.com/developers/gabi/</xref>). A tool is
+therefore needed to convert from the ELF format into the E32Image format,
+and this is the key role of the post-linker. The tool also contains the functionality
+to maintain and create the DEF files used for freezing the exports of libraries. </p>
+<p>In ordinary use, the post-linker is not used directly by users. It is called
+from the makefiles generated by <filepath>abld</filepath> on the command line,
+or from the build commands of an IDE. </p>
+<p>The tool can also be used to <xref href="GUID-6A5D3E05-B1F4-4DF6-9384-3CC471DCC267.dita">output
+a description</xref> of an existing E32Image file for analysis. </p>
