dnl
dnl Arguments:	PACKAGE = package name
dnl		VERSION = version number
dnl		NO-DEFINE = if set, don't define package and version number
dnl
dnl Use:	Do all the work for Automake.  This macro actually does too
dnl		much -- some checks are only needed if your package does
dnl		certain things.  But this isn't really a big deal.
