<h2 id="translate">Translate</h2>
<h3>Description</h3>
<p>Identifies keys in files delimited by special tokens and translates them with values read from
resource bundles.</p>
<p>A resource bundle contains locale-specific key-value pairs.  A resource bundle is a hierarchical
set of property files.  A bundle name makes up its base family name.  Each file that makes up this
bundle has this name plus its locale.  For example, if the resource bundle name
is <samp>MyResources</samp>, the file that contains German text will take the
name <samp>MyResources_de</samp>.  In addition to language, country and variant are also used to
form the files in the bundle.</p>
<p>The resource bundle lookup searches for resource files with various suffixes on the basis of (1)
the desired locale and (2) the default locale (basebundlename), in the following order from
lower-level (more specific) to parent-level (less specific):</p>
<pre>
basebundlename + &quot;_&quot; + language1 + &quot;_&quot; + country1 + &quot;_&quot; + variant1
basebundlename + &quot;_&quot; + language1 + &quot;_&quot; + country1
basebundlename + &quot;_&quot; + language1
basebundlename
basebundlename + &quot;_&quot; + language2 + &quot;_&quot; + country2 + &quot;_&quot; + variant2
basebundlename + &quot;_&quot; + language2 + &quot;_&quot; + country2
basebundlename + &quot;_&quot; + language2
</pre>
<p>The file names generated thus are appended with the string <samp>.properties</samp> to make up
the file names that are to be used.</p>
<p>File encoding is supported.  The encoding scheme of the source files, destination files and the
bundle files can be specified.</p>
<p>Destination files can be explicitly overwritten using the <var>forceoverwrite</var> attribute.
If <var>forceoverwrite</var> is <q>false</q>, the destination file is overwritten only if either the
source file or any of the files that make up the bundle have been modified after the destination
file was last modified.</p>
<p><em>Since Apache Ant 1.6</em> line endings of source files are preserved in the translated
files.</p>
<p><a href="../Types/fileset.html">FileSet</a>s are used to select files to translate.</p>
