module for reading/writing Microsoft Excel spreadsheet files

 Xlwt is a Python module for generating .xls spreadsheet files compatible with
 Excel 97/2000/XP/2003, OpenOffice.org Calc, and Gnumeric. Excel spreadsheets
 can be generated on any platform without needing Excel or a COM server. The
 only requirement is Python 2.3 to 2.6. Xlwt is a fork of the unmaintained
 pyExcelerator.
