Moving the data manipulation stuff to an extra module certainly sounds like a good idea to me ... we could think of it as an extended version of rrdtool fetch ... how would you go about it? What aobut the interfaces ? cheers tobi | cheers, | -- ______ __ _ /_ __/_ / / (_) Oetiker, ETZ J97, ETH, 8092 Zurich, Switzerland / // _ \/ _ \/ / phoneto:+41(0)1-632-5286 faxto:+41(0)1-632-1517 /_/ \.__/_.__/_/ mailto:[EMAIL PROTECTED] http://people.ee.ethz.ch/~oetiker -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-developers WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
