4 dnl Created by Jeff Allen, Tobi Oetiker, Blair Zajac
5 dnl
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],[1.3rc6])
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=1.299908052600
20 AC_SUBST(NUMVERS)
22 dnl for the linker to understand which version the library is compatible with
23 dnl we must keep a separate library version cout of the format c:r:a if any
24 dnl functionality is changed do c++ prior to release
25 dnl if only implementation changed but all interfaces are kept, do r++
26 dnl when only functionality was added, do a++ if any functionality was
27 dnl removed do a=0.
