The mvc.themes or name property specifies the name for the theme which will be displayed in the Runtime theme selector. The other two properties specify which StringTemplate index file should be used and which StringTemplate function should be called to render the index page (see "Creating the index file" above). The path to the index file is relative to either the JAR/DLL or the
/Configuration folder. When a file name is specified which is located in Include Page _ConfigLocation _ConfigLocation
/Configuration and that is already loaded from a JAR, the file from Include Page _ConfigLocation _ConfigLocation
/Configuration will be used and the file from the JAR/DLL will be overridden. More information about overriding existing themes can be found on Extending themes. Include Page _ConfigLocation _ConfigLocation
