+Here is an oddity whose solution was discovered by Jan Matèrne. In Ant, what

'''not''' have an extension in a directory tree.
You might think you could just specify that the included files end in a
period, like so:
-{{{ <fileset includes="**/*." /> }}}
+{{{ <fileset includes="**/*." /> }}}
but that will only select files which literally end in a period. The actual
answer is a bit counterintuitive. You select all files (implicit) and then
exclude those that have an extension:
-{{{ <fileset excludes="*.*" /> }}}
+{{{ <fileset excludes="*.*" /> }}}
== Changing default Locale ==
When I worked with CheckStyle I realized that there are localized message. So
far so fine. But now I want to generate an international (English) site on my
(German) machine. But how to realize that?
-CheckStyle - like many other programs - uses the
java.util.ResourceBundle.getBundle() method which returns the appropriate
bundle for the '''default''' Locale. So I will set the default Locale to the US
value. Before that I store the actual one (or the 'key') as property and
restore that after invoking CheckStyle. Because I need (simple) access to the
Java API, I write that inside <script> tasks:
