This will convert a command file containing only commands to NCP to a
 command file containing equivalent commands to NCL.  Commands must be
 of the following form to be converted:

     <command-line>
     <command-line>
     <command-line>

 The commands should appear as they would if they were typed directly
 to the "NCP>" prompt.

 The conversion will generally not be complete, due to the differences
 between NCP and NCL.  Some additional editing will be required before
 the NCL commands may be used.

 The source NCP commands will be preserved in the target file as comment
 lines, to help provide a reference for determining how NCP commands were
 converted to NCL.

 Example:  CONVERT NCP_FILE CIRCUITS.COM
