4 dnl Created by Jeff Allen, Tobi Oetiker, Blair Zajac
6 dnl Inspiration from http://autoconf-archive.cryp.to
8 dnl tell automake the this script is for rrdtool
9 dnl the official version number is
11 AC_INIT([rrdtool],[1.2.11])
12 dnl for testing a numberical version number comes handy
13 dnl the released version are
15 dnl the devl versions will be something like
21 AC_CONFIG_HEADERS([config.h])
23 dnl all our local stuff like install scripts and include files
27 dnl determine the type of system we are running on
