How do I call a function from the other CFC

Hi,

Is there the way to call the function from other cfc?

From cfc.message, how can i call the method "getuser" from user.cfc

<cfcomponent name="user">

    <cffunction name="getuser">

    </cffunction>

</cfcomponent>

<cfcomponent name="message">

    <cffunction name="get_message">

    </cffunction>

</cfcomponent>

Thanks
