11*Module G2export_examples: Examples*
12-------------------------------------------
13
14Code to demonstrate how GSAS-II data export routines are created. The
15classes defined here, :class:`ExportPhaseText`,
16:class:`ExportSingleText`, :class:`ExportPowderReflText`,
17and :class:`ExportPowderText` each demonstrate a different type
18of export. Also see :class:`G2export_map.ExportMapASCII` for an
19example of a map export.
