dnl
dnl AS_VERSION(PACKAGE, PREFIX, MAJOR, MINOR, MICRO, NANO, ACTION_IF_NO_NANO, ACTION_IF_NANO)
dnl example
dnl AS_VERSION(gstreamer, GST_VERSION, 0, 3, 2,)
dnl for a 0.3.2 release version
dnl
dnl this macro
dnl - defines [$PREFIX]_MAJOR, MINOR and MICRO
dnl - if NANO is empty, then we're in release mode, else in cvs/dev mode
dnl - defines [$PREFIX], VERSION, and [$PREFIX]_RELEASE
dnl - executes the relevant action
dnl - AC_SUBST's PACKAGE, VERSION, [$PREFIX] and [$PREFIX]_RELEASE
dnl   as well as the little ones
dnl - doesn't call AM_INIT_AUTOMAKE anymore because it prevents
dnl   maintainer mode from running ok
dnl
dnl don't forget to put #undef [$2] and [$2]_RELEASE in acconfig.h
