<h3>MODULE SUMMARY</h3>
<div class="REFBODY">Main API of the Reltool application</div>
<h3>DESCRIPTION</h3>
<div class="REFBODY"><p>
<p>This is an interface module for the Reltool application.</p>
<p><strong>Reltool</strong> is a release management tool. It analyses a
given Erlang/OTP installation and determines various dependencies
between applications. The <span class="code">graphical</span> frontend depicts the
dependencies and enables interactive customization of a target
system. The backend provides a <span class="code">batch</span> interface for
generation of customized target systems.</p>
<p>The tool uses an installed Erlang/OTP system as input.
<span class="code">root_dir</span> is the root directory of the analysed system and
it defaults to the system executing <span class="code">reltool</span>. Applications
may also be located outside <span class="code">root_dir</span>. <span class="code">lib_dirs</span>
defines additional library directories where applications
additional may reside and it defaults to the the directories
listed by the operating system environment variable
<span class="code">ERL_LIBS</span>. See the module <span class="code">code</span> for more info.
Finally single modules and entire applications may be read from
Escripts.</p>
<p>Some configuration parameters control the behavior of Reltool
on system (<span class="code">sys</span>) level. Others provide control on
application (<span class="code">app</span>) level and yet others are on module
(<span class="code">mod</span>) level. Module level parameters overrides application
level parameters and application level parameters overrides system
level parameters. Escript <span class="code">escript</span> level parameters
overrides system level parameters.</p>
<p>The following top level <span class="code">options</span> are supported:</p>
<dl>
<dt><strong><span class="code">config</span></strong></dt>
<dd>
<p>This is the main option and it controls the configuration
of <span class="code">reltool</span>. It can either be a <span class="code">sys</span> tuple or
a name of a <span class="code">file</span> containing a sys tuple.</p>
</dd>
<dt><strong><span class="code">trap_exit</span></strong></dt>
<dd>
<p>This option controls the error handling behavior of
<span class="code">reltool</span>. By default the window processes traps
exit, but this behavior can altered by setting
<span class="code">trap_exit</span> to <span class="code">false</span>.</p>
</dd>
<dt><strong><span class="code">wx_debug</span></strong></dt>
<dd>
<p>This option controls the debug level of <span class="code">wx</span>. As its
name indicates it is only useful for debugging. See
<span class="code">wx:debug/1</span> for more info.</p>
</dd>
</dl>
<p>Besides the already mentioned source parameters <span class="code">root_dir</span>
and <span class="code">lib_dirs</span>, the following system (<span class="code">sys</span>) level
options are supported:</p>
<dl>
<dt><strong><span class="code">erts</span></strong></dt>
<dd>
<p>Erts specific configuration. See application level options
below.</p>
</dd>
<dt><strong><span class="code">escript</span></strong></dt>
<dd>
<p>Escript specific configuration. An escript has a mandatory
file name and escript level options that are described
below.</p>
</dd>
<dt><strong><span class="code">app</span></strong></dt>
<dd>
<p>Application specific configuration. An application has a
mandatory name and application level options that are
described below.</p>
</dd>
<dt><strong><span class="code">mod_cond</span></strong></dt>
<dd>
<p>This parameter controls the module inclusion policy. It
defaults to <span class="code">all</span> which means that if an application is
included (either explicitly or implicitly) all modules in that
application will be included. This implies that both modules
that exists on the <span class="code">ebin</span> directory of the application,
as well as modules that are named in the <span class="code">app</span> file will
be included. If the parameter is set to <span class="code">ebin</span>, both
modules on the <span class="code">ebin</span> directory and derived modules are
included. If the parameter is set to <span class="code">app</span>, both modules
in the <span class="code">app</span> file and derived modules are included.
<span class="code">derived</span> means that only modules that are used by other
included modules are included. The <span class="code">mod_cond</span> setting on
system level is used as default for all applications.</p>
</dd>
<dt><strong><span class="code">incl_cond</span></strong></dt>
<dd>
<p>This parameter controls the application and escript
inclusion policy. It defaults to <span class="code">derived</span> which means
that the applications that not have any explicit
<span class="code">incl_cond</span> setting, will only be included if any other
(explicitly or implicitly included) application uses it. The
value <span class="code">include</span> implies that all applications and
escripts that that not have any explicit <span class="code">incl_cond</span>
setting will be included. <span class="code">exclude</span> implies that all
applications and escripts) that that not have any explicit
<span class="code">incl_cond</span> setting will be excluded.</p>
</dd>
<dt><strong><span class="code">boot_rel</span></strong></dt>
<dd>
<p>A target system may have several releases but the one given
as <span class="code">boot_rel</span> will be used as default when the system is
booting up.</p>
</dd>
<dt><strong><span class="code">rel</span></strong></dt>
<dd>
<p>Release specific configuration. Each release maps to a
<span class="code">rel</span>, <span class="code">script</span> and <span class="code">boot </span> file. See the
module <span class="code">systools</span> for more info about the details. Each
release has a name, a version and a set of applications with a
few release specific parameters such as type and included
applications.</p>
</dd>
<dt><strong><span class="code">relocatable</span></strong></dt>
<dd>
<p>This parameter controls whether the <span class="code">erl</span> executable
in the target system automatically should determine where it
is installed or if it should use a hardcoded path to the
installation. In the latter case the target system must be
installed with <span class="code">reltool:install/2</span> before it can be
used. If the system is relocatable, the file tree containing
the target system can be moved to another location without
re-installation. The default is <span class="code">true</span>.</p>
</dd>
<dt><strong><span class="code">profile</span></strong></dt>
<dd>
<p>The creation of the specification for a target system is
performed in two steps. In the first step a complete
specification is generated. It will likely contain much more
files than you are interested in your customized target
system. In the second step the specification will be filtered
according to your filters. There you have the ability to
specify filters per application as well as system wide
filters. You can also select a <span class="code">profile</span> for your
system. Depending on the <span class="code">profile</span>, different default
filters will be used. There are three different profiles to
choose from: <span class="code">development</span>, <span class="code">embedded</span> and
<span class="code">standalone</span>. <span class="code">development</span> is default. The
parameters that are affected by the <span class="code">profile</span> are:
<span class="code">incl_sys_filters</span>, <span class="code">excl_sys_filters</span>,
<span class="code">incl_app_filters</span> and <span class="code">excl_app_filters</span>.</p>
</dd>
<dt><strong><span class="code">app_file</span></strong></dt>
<dd>
<p>This parameter controls the default handling of the
<span class="code">app</span> files when a target system is generated. It
defaults to <span class="code">keep</span> which means that <span class="code">app</span> files are
copied to the target system and their contents are kept as
they are. <span class="code">strip</span> means that a new <span class="code">app</span> file is
generated from the contents of the original <span class="code">app</span> file
where the non included modules are removed from the
file. <span class="code">all</span> does also imply that a new <span class="code">app</span> file is
generated from the contents of the original <span class="code">app</span> file,
with the difference that all included modules are added to the
file. If the application does not have any <span class="code">app</span> file a
file will be created for <span class="code">all</span> but not for <span class="code">keep</span>
and <span class="code">strip</span>.</p>
</dd>
<dt><strong><span class="code">debug_info</span></strong></dt>
<dd>
<p>The <span class="code">debug_info</span> parameter controls whether the debug
information in the beam file should be kept (<span class="code">keep</span>) or
stripped <span class="code">strip</span> when the file is copied to the target
system.</p>
</dd>
<dt><strong><span class="code">incl_sys_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which files in the system that
should be included. Each file in the target system must match
at least one of the listed regular expressions in order to be
included. Further the files may not match any filter in
<span class="code">excl_sys_filters</span> in order to be included. Which
application files that should be included are controlled with
the parameters <span class="code">incl_app_filters</span> and
<span class="code">excl_app_filters</span>. This parameter defaults to
<span class="code">[".*"]</span>.</p>
</dd>
<dt><strong><span class="code">excl_sys_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which files in the system that not
should be included in the target system. In order to be
included, a file must match some filter in
<span class="code">incl_sys_filters</span> but not any filter in
<span class="code">excl_sys_filters</span>. This parameter defaults to
<span class="code">[]</span>.</p>
</dd>
<dt><strong><span class="code">incl_app_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which application specific files
that should be included. Each file in the application must
match at least one of the listed regular expressions in order
to be included. Further the files may not match any filter in
<span class="code">excl_app_filters</span> in order to be included. This
parameter defaults to <span class="code">[".*"]</span>.</p>
</dd>
<dt><strong><span class="code">excl_app_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which application specific files
that not should be included in the target system. In order to
be included, a file must match some filter in
<span class="code">incl_app_filters</span> but not any filter in
<span class="code">excl_app_filters</span>. This parameter defaults to
<span class="code">[]</span>.</p>
</dd>
<dt><strong><span class="code">incl_archive_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which top level directories in an
application that should be included in an archive file (as
opposed of beeing included as a regular directory outside the
archive). Each top directory in the application must match at
least one of the listed regular expressions in order to be
included. Further the files may not match any filter in
<span class="code">excl_app_filters</span> in order to be included. This
parameter defaults to <span class="code">[".*"]</span>.</p>
</dd>
<dt><strong><span class="code">excl_archive_filters</span></strong></dt>
<dd>
<p>This parameter normally contains a list of regular
expressions that controls which top level directories in an
application that not should be included in an archive file. In
order to be included in the application archive, a top
directory must match some filter in <span class="code">incl_archive_filters</span>
but not any filter in <span class="code">excl_archive_filters</span>. This
parameter defaults to <span class="code">["^include$","^priv$"]</span>.</p>
</dd>
<dt><strong><span class="code">archive_opts</span></strong></dt>
<dd>
<p>This parameter contains a list of options that are given to
<span class="code">zip:create/3</span> when application specific files are
packaged into an archive. All options are not supported. The
most useful options in this context, are the ones that
controls which types of files that should be compressed. This
parameter defaults to <span class="code">[]</span>.</p>
</dd>

supported:</p>
<dl>
<dt><strong><span class="code">vsn</span></strong></dt>
<dd>
<p>The version of the application. In an installed system there may
exist several versions of an application. The <span class="code">vsn</span> parameter
controls which version of the application that will be choosen. If it
is omitted, the latest version will be choosen.</p>
