 dnl AS_VERSION(PACKAGE, PREFIX, MAJOR, MINOR, MICRO, NANO,

 dnl            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 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

 dnl if you use acconfig.h
