- **-h 5**

- **-d**

  make a XML based definition file used for validating NeXus files (i.e. remove the data).

- **-o keepws**

  the XML file created should preserve whitespace.

- **-o table**

  the XML file created should write the data in a table format where the columns and rows are easily imported into spreadsheet programs.
