There is interesting question: How old are ebuilds in tree? (in term when they were touched last time)

So using simple oneliner we can gather ebuilds by year

# for i in `seq 2004 2010`; do echo -n "${i} "; qgrep -e "\-${i} Gentoo" | wc -l; done



Since we currently has 4 active EAPI’s in tree another interesting question was: How EAPI’s are distributed across tree?
