"""Convert CSV table to MindMap format

Usage: python csv_to_mm.py sometable.csv > mymap.mm

CSV format is rows representing tree leaves, e.g.:
    A1,
    A1,B1
    A1,B1,C1
    A1,B1,C2
    A2,B2

Parses into the following tree:
    A1
      B1
        C1
        C2
    A2
      B2

It doesn't run. I try with a simple csv file and the mm file created is 0 bytes. Probably I'm doing anything wrong, but I don't know what. The Free Mind version is 0.9.0

This worked for me, thanks!

Python27 on Windows 7 with the http://pypi.python.org/pypi/xmlbuilder library installed. Freemind 1.0.0.

It worked for me Ubuntu 14.04- freemind 0.9.
My file had you have to remove this line to make it work.
Thanks a lot gpoulter :)
