dnl tell automake the this script is for rrdtool
dnl the official version number is
dnl a.b.c
-AC_INIT([rrdtool],[1.2.10])
+AC_INIT([rrdtool],[1.2.11])
dnl for testing a numberical version number comes handy
dnl the released version are
dnl a.bccc
dnl the devl versions will be something like
dnl a.b999yymmddhh
-NUMVERS=1.2010
