would you mind elaborating on these statistics a bit more? Right now i
don't know whether i am putting them together correctly.

- What exactly are the figures in the Total column? Currently available
packages released in that year? So we would still have one package each
from back in 1997 and 1998?

So taking for example the "Delta of packages in may is +105". Does it
mean, we released 105 packages in May (either updated or new) that
haven't been available in a 2009 revision before (thus contributing to
the Total 2009 figure)? This would be quite neat. And +530 would be 530
updated/released packages in 2009? Why would it differ from the Total
number of 508 then?

Getting back to another year, taking 2008 for example. Do we have 304
packages in the catalog which are from 2008? Have we updated/dropped 35
of them last month and 173 over the course of this year?
