[turba] Cannot import CSV Adressbook

[Ferdinand Gruber]

I tried to to import the Thunderbird Adressbook into Turba.
I exported TB Adressbook as CSV
But now I am not able to import the data into turba.

I tried some variants.

Thunderbird does not make quotes at the beginning and at the end of each 
data item. Therefore I loaded the CSV into LibreOffice Calc and exported 
with quotes.
But nothing helped.

The Import tool of turba does not show the field list of the imported 
addressbook.

May be, I am too stupid ...

Please help, I spent some hours for this problem without solution.

Please, give me an example of a file with some records, so that I can 
see, how the data have to be formatted, so that the import is possible.
