9 dnl tell automake the this script is for rrdtool
11 dnl Minimum Autoconf version required.
14 dnl the official version number is
16 AC_INIT([rrdtool],[1.3.999])
18 dnl for testing a numberical version number comes handy
19 dnl the released version are
21 dnl the devel versions will be something like
26 dnl for the linker to understand which versions the library are compatible with
27 dnl each other we must keep a separate library version cout of the format c:r:a.
28 dnl - if only implementation changed but all interfaces are kept, do r++
29 dnl - if only functionality was added do c++,r=0,a++
30 dnl - if any functionality was removed do c++,r=0,a=0.
