I have added the branch "rrdmodify-master" to the git repo at

This is essentially a rebase of rrdmodify from its branching point at
1.4 to master, so it does not contain anything not created by me. It
should work just as well as the rrdmodify branch. So: please pull!

Note that the branch contains some changes that might be useful for
other things as well: I factored out parseDS and avoided some code
duplication in rrd_client.c (rrd_flush / rrd_forget use a common
function that might be reused for other filename based rrdcached
commands). One goal should definitly be (read: 2.0) to get rid of code
duplication and  become more modular overall.

I'll look into RRA modification...
