6 dnl Inspiration from http://autoconf-archive.cryp.to
8 dnl tell automake the this script is for rrdtool
10 dnl the official version number is
11 dnl a.b.c
12 AC_INIT([rrdtool],[1.3.2])
14 dnl for testing a numberical version number comes handy
15 dnl the released version are
16 dnl a.bccc
17 dnl the devel versions will be something like
18 dnl a.b999yymmddhh
19 NUMVERS=1.3002
20 AC_SUBST(NUMVERS)
22 dnl for the linker to understand which versions the library are compatible with
23 dnl each other we must keep a separate library version cout of the format c:r:a.
24 dnl - if only implementation changed but all interfaces are kept, do r++
25 dnl - if only functionality was added do c++,r=0,a++
26 dnl - if any functionality was removed do c++,r=0,a=0.
