10 dnl a.b.c
11 AC_INIT([rrdtool],[1.2.99907052400])
12 dnl for testing a numberical version number comes handy
13 dnl the released version are
14 dnl a.bccc
15 dnl the devel versions will be something like

18 AC_SUBST(NUMVERS)
19 AC_CANONICAL_TARGET
20 AM_INIT_AUTOMAKE
21 AC_CONFIG_HEADERS([rrd_config.h])
23 dnl all our local stuff like install scripts and include files
