[Tutor] Using python to create and save a Ms Word file

Hi Everyone,


I wasn't entirely satisfied with the Ms Word solution because it
requires the program run on Windows and have Office installed.

As an alternate solution, I created the program listed below to read a
file and create a RTF file format document from it.

The program is not platform dependent but it does require installation
of the PyRTF module.

I hope someone finds this useful/interesting.


#!C:\Python24\python
#
# program: rtfmaker.py
# Author:  Andrew Robert
#
# Function: Take a supplied file and dump its contents to an RTF file
#           This code is platform independant.
