Lets say you have a project that uses two cfcomponent files, a.cfc and b.cfc.
You have functions in a.cfc that you'd like to be available within b.cfc, for example, within a.cfc is a debug handler that I would want to be used inside of cffuctions within b.cfc
You could, within component b, invoke the function like this:
<cfset a_object = createobject("component","dotted_path_to_component_a")>
<cfset result = a_object.function_in_a()>
