Importing a vcf file into contacts

I would like to be able to import my contacts into opendesktop. I have a vcf file which I exported from Google.

What language is opendesktop written in? I am currently working in python but I’ve been programming for 50 years, I started at 10 years old on PDP 8. I’d be willing to roll up my shirt sleeves and give a hand as I am sure other people would like to be able to import contacts instead of having to enter them all manually.
