# OBSOLETE MACRO
#
#   Superseded by AC_SET_VERSIONLEVEL.
#
# SYNOPSIS
#
#   AC_DEFINE_VERSIONLEVEL(VARNAME [,VERSION [, DESCRIPTION]])
#
# DESCRIPTION
#
#   if the VERSION is ommitted, shellvar $VERSION is used as defined by
#   AM_INIT_AUTOMAKE's second argument.
#
#   The versionlevel is the numeric representation of the given version
#   string, thereby assuming the inputversion is a string with
#   (maximal) three decimal numbers seperated by "."-dots. A "-patch"
#   adds a percent.
#
#   typical usage: AM_INIT_AUTOMAKE(mypkg,4.12.3)
#   AC_DEFINE_VERSIONLEVEL(MYPKG_VERSION)
#
#   the config.h created from autoheader's config.h.in will contain...
#   /* mypkg versionlevel */ #define MYPKG_VERSION 4120003
#
#   the MYKG_VERSION will be defined as both a shell-variable and
#   AC_DEFINE
#
#   examples:
#
#          3.0-beta1     3000001
#          3.1           3010000
#          3.11          3110000
#          3.11-dirpatch 3111000
#          3.11-patch6   3110006
#          2.2.18        2020018
#          2.0.112       2000112
#          2.4.2         2040002
#          2.4.2-pre     2040003
#          2.4.2-pre5    2040003
#          5.0-build125  5000125
#          5.0           5000000
