I don't know if there is a "classical" way to do it;
but maybe you could overwrite lint.Pylinter.get_astng to return
logilab.astng.builder.ASTNGBuilder.string_build(script_created_by_user)
But that's only half of the job; you will need to use the --init-hook
option to activate the scriptglobals
hope, that helps ;)
