35  * in the IDE's GUI: i.e. both <code>build.xml</code> and <code>build-impl.xml</code>
36  * will be regenerated if they are missing, or if they are out of date with
37  * respect to either <code>project.xml</code> or the stylesheet (and are
38  * not modified according to <code>genfiles.properties</code>).
