[away3d] objects from a main file

[Radioactivelizard]

i'm attempting to create a AS3 script that loads another script that
will in turn load models  to my scene

-----Main.as--------

  function main()
      {
         include "MyBSPProject.as"
                 }
------------------------
if i set MyBSPProject.AS as always compile it compiles and loads
correctly
when loaded from main.as i get. "Error: Classes must not be nested"

the error comes from MyBSPProject.as (MyBSPProject.as is created by
prefab)

am i going about this the wrong way by attempting it as a include
statement?
