rosfran@253: dnl - defines [$PREFIX]_MAJOR, MINOR and MICRO
rosfran@253: dnl - if NANO is empty, then we're in release mode, else in cvs/dev mode
rosfran@253: dnl - defines [$PREFIX], VERSION, and [$PREFIX]_RELEASE
rosfran@253: dnl - executes the relevant action
rosfran@253: dnl - AC_SUBST's PACKAGE, VERSION, [$PREFIX] and [$PREFIX]_RELEASE
rosfran@253: dnl   as well as the little ones
rosfran@253: dnl - doesn't call AM_INIT_AUTOMAKE anymore because it prevents

rosfran@253: dnl
rosfran@253: dnl don't forget to put #undef [$2] and [$2]_RELEASE in acconfig.h
