Today you sent me mail regarding Re: [rrd-developers] Re: proposal for...:

*>  (2) pretty printing the last update of a given RRD...
*>

sure ... I just think that it is pretty simple to have a single function
which does both ... you can give it either the name of an RRD or an AT-Time
descr ... (argument overloading)
