12 | ------------------------------------------- |

13 | |
---|
14 | Code to demonstrate how GSAS-II data export routines are created. The |

15 | classes defined here, :class:`ExportPhaseText`, |
---|
16 | :class:`ExportSingleText`, :class:`ExportPowderReflText`, |
---|
17 | and :class:`ExportPowderText` each demonstrate a different type |
---|
18 | of export. Also see :class:`G2export_map.ExportMapASCII` for an |
---|
19 | example of a map export. |
