Description: XML description of machine configuration database metadata
This file defines the languages, options, and valid option choices for
the Babel machine configuration database.
To add a new language to the Babel compiler, you must add a new Language
element and provide any necessary configuration options and parameters.
-->
<!DOCTYPE ConfigurationMetadata SYSTEM "metadata.dtd">
<!--
The ConfigurationMetadata element is the root element of the metadata
description. To add support for a new language for the Babel compiler,
add a new Language element to ConfigurationMetadata.

The C configuration does not support any options at this time.

<!--
The Babel compiler for C++ supports the following options:
use namespaces generate subs/skels with/without namespaces
have reinterpret cast whether compiler supports reinterpret_cast
-->
<Language name="C++">
<Option name="use namespaces">
<Comment summary="use C++ namespaces in generated code">
Option <em>use namespaces</em> determines whether the Babel
compiler is allowed to use C++ namespaces in stubs and skeletons
to represent sidl packages. Possible choices are <var>true</var>
and <var>false</var>. If <em>use namespaces</em> is <var>true</var>,
then the Babel compiler will represent a sidl package named
<code>Package.Class</code> as <code>Package::Class</code> in C++;
otherwise, an underscore will be used (<code>Package_Class</code>).

</Option>
<Option name="have reinterpret cast">
<Comment summary="whether C++ compiler supports reinterpret_cast">
Option <em>have reinterpret cast</em> determines whether the
Babel compiler uses the <code>reinterpret_cast</code> run-time
type identification feature of C++. Some C++ compilers do not
yet support advanced type identification features. Valid choices
are <var>true</var> and <var>false</var>.
