Spending a minute in copyright metric

Here is for addons

chanon@batman:~/openerp-REG/openerp/addons$ find . -name *.py -exec grep Copyright {} \;  | wc -l
776
chanon@batman:~/openerp-REG/openerp/addons$ find . -name *.py -exec grep Copyright {} \;  | grep Tiny | wc -l
718

And for addons-extra

chanon@batman:~/openerp-REG/openerp/addons-extra$ find . -name *.py -exec grep Copyright {} \;  | wc -l
1789
chanon@batman:~/openerp-REG/openerp/addons-extra$ find . -name *.py -exec grep Copyright {} \;  | grep Tiny | wc -l
1193

So 10% in the first case and 30% in the second one. I will try to elaborate more on these figures.
