+** This is a template build file for a JOSM  plugin.
+**
+** Maintaining versions
+** ====================
+** see README.template
+**
+** Usage
+** =====
+** To build it run
+**
+**    > ant  dist
+**
+** To install the generated plugin locally (in you default plugin directory) run
+**
+**    > ant  install
+**
+** The generated plugin jar is not automatically available in JOSMs plugin configuration
+** dialog. You have to check it in first.
+**
+** Use the ant target 'publish' to check in the plugin and make it available to other
+** JOSM users:
+**    set the properties commit.message and plugin.main.version
+** and run
+**    > ant  publish
+**
