- &lt;Erlang root&gt;\\releases). The
- <c><![CDATA[start_erl.data]]></c> file is expected to be
- placed in this directory (if not otherwise specified). If

- <c>erts-&lt;Version&gt;</c> directories are placed). If only
- <c>-reldir</c> (or the environment variable

- <item>Optional, specifies another data file than start_erl.data
- in the &lt;release root&gt;. It is specified relative to the
- &lt;release root&gt; or absolute (including drive letter

- upgrade and should not be used during normal
- operation. The release data file should not normally be
- named differently.</item>
- <tag>-bootflags &lt;boot flags file name&gt;</tag>
- <item>Optional, specifies a file name relative to actual release
- directory (that is the subdirectory of &lt;release
- root&gt; where the <c><![CDATA[.boot]]></c> file etc. are placed).
- The contents of this file is appended to the command line
- when Erlang is started. This makes it easy to start the

- <p>As the source code is distributed, it can easily be modified to

- <p>The Erlang emulator is found by examining the registry keys for
- the emulator version specified in the release data file. The new
- emulator needs to be properly installed before the upgrade for
- this to work.</p>
- <p>Although the program is located together with files specific to
- emulator version, it is not expected to be specific to the
- emulator version. The release handler does <em>not</em> change the
- <c><![CDATA[-machine]]></c> option to <c><![CDATA[erlsrv]]></c> during emulator restart.
- Place the (possibly customized) <c><![CDATA[start_erl]]></c> program so that
- it is not overwritten during upgrade. </p>
- <p>The <c><![CDATA[erlsrv]]></c> program's default options are not
- sufficient for release handling. The machine <c><![CDATA[erlsrv]]></c>
- starts should be specified as the <c><![CDATA[start_erl]]></c> program and
