This page will soon be removed and I will no longer continue develop chmosx. But the code will still be available at sourceforge. If anyone wants to take over the sourceforge page, please let me know.
You may want to check out more software for Mac, such as wxFormBuilder, TopCoder UML Tool or Jaxe, which might be similar to chmosx.
