Dive computer tool for blind and visually impaired divers

[Simon Eigeldinger]

Hi Willem,

thanks for the info.
well i need just the dc data anyway.
so maybe just importing the dc data, exporting all things and then use 
the csv data might be enough.
then not saving the logbook xml file.

xml isn't nice to be used mainly as info for blind people so xml isn't 
the way i think i might use my data.
xml is human readable but not convenient. *smile*

I guess dctool also might to be able to download the dives but not be 
able to convert that to csv.

Greetings,
Simon
