<?xml version="1.0" encoding="utf-8"?>
<module rename-to='MyApp'>
   <!-- inherit the core web toolkit stuff.  -->
   <inherits name='com.google.gwt.user.user'/>

   <!-- inherit the default gwt style sheet. -->
   <inherits name='com.google.gwt.user.theme.clean.Clean'/>

   <!-- specify the app entry point class. -->
   <entry-point class='com.example.client.MyApp'/>

   <!-- specify the paths for translatable code (the below folders get complied to JS)  -->
   <source path='client'/>
   <source path='shared'/>

   <!-- specify the paths for static files like html, css etc. -->
   <public path='...'/>
   <public path='...'/>

   <!-- specify the paths for external javascript files -->
   <script src="js-url" />
   <script src="js-url" />

   <!-- specify the paths for external style sheet files  -->
   <stylesheet  src="css-url" />
   <stylesheet  src="css-url" />

</module>
