!This is a data converter program. Its actions are controlled by
!the registry and the namelist.  It will read variables on the
!'i' stream output and output variables on the 'o' stream as
!indicated in the registry. The input and output forms are 
!controlled by io_form_input and io_form_history in the namelist.input.
