<p>
Honor start type in .rel files when building relup files</p>
<p>
Previously, relup file always included an
application:start(Application, permanent) apply
instruction for every application that appear in the
UpTo/DowFrom release file, whatever their start type in
the release file.</p>
<p>
The new implementation fixes this bug by honoring the
start type according to the rel(5) format. If the start
type is none, no apply line is included in the relup. If
the start type is load, the relup includes instruction to
only load the application. Otherwise, the relup includes
an instruction to start the application to the according
type.</p>
<p>
The fix is implemented by adding a new parameter to the
add_application high level appup instruction. This new
parameter is documented in appup(5).</p>

<section><title>Fixed Bugs and Malfunctions</title>
<list>
<item>
<p>In R13B04 sys:get_status was modified to invoke
format_status/2 in the callback module if the module
exports that function. This resulted in a change to the
term returned from calling sys:get_status on the
supervisor module, since supervisor is a gen_server and
gen_server exports format_status. The sasl
release_handler_1 module had a dependency on the
pre-R13B04 term returned by sys:get_status when invoked
on a supervisor, so the R13B04 change broke that
dependency.</p>
<p>This problem has been fixed by change
release_handler_1 to handle both the pre-R13B04 and
R13B04 terms that sys:get_status can return from a
supervisor.</p>

<p>
The <c>re:grep/1</c> function now uses the '<c>re</c>'
module instead of the deprecated '<c>regexp</c>' module.
There are new functions <c>rb:filter/1</c> and
<c>rb:filter/2</c> for easier filtering of reports.

<p>
There is new function <c>sasl_report:format_report/3</c>
that works like the existing
<c>sasl_report:write_report/3</c> function except that it
returns a formatted string. Note that there is currently
no documentation for the <c>sasl_report</c> module.
(Thanks to Jay Nelson.)</p>

<item>
<p>Added an option <c>{outdir,Dir}</c> to the functions in
<c>systools</c>, making it possible to specify in which
directory a boot script, relup file or release package
file should be placed.</p>
<p>Also, when using <c>systools:make_tar/2</c> to create a
release package file, the boot script, relup file and
<c>sys.config</c> are now searched for also in the current
working directory and any directory specified by
the <c>path</c> option, not only in the directory of
the <c>.rel</c> file.</p>
<p>As part of the work some minor bugs have been corrected:</p>
<list type="bulleted">
<item>
<p><c>systools:make_script/1,2</c> now returns
<c>error</c> if the <c>.script</c> and/or <c>.boot</c>
file could not be opened for writing, not <c>ok</c>.</p>
</item>
<item>
<p><c>systools:make_tar/1,2</c> can now handle a
<c>RelName</c> argument which includes a path.
Previously this would cause the <c>.rel</c> file to end
up in the wrong directory in the resulting tar file.</p>
</item>
<item>
<p>A documentation error for <c>systools:make_tar/1,2</c>:
The <c>.rel</c> file is placed in the <c>releases</c>
directory in the tar file, not <c>releases/RelVsn</c>.</p>
