The `Makefile.am` file one level higher is as follows. ACLOCAL_AMFLAGS = -I gnulib/m4 -I m4 SUBDIRS = gnulib/src \ lib \ frontend \ doc EXTRA_DIST = bootstrap \ bootstrap.conf \ FTL.TXT \ gnulib/m4/gnulib-cache.m4 \ GPLv2.TXT \ README \ TODO \ .version BUILT_SOURCES = .version .version: echo $(VERSION) > $@-t && mv $@-t $@ dist-hook: echo $(VERSION) > $(distdir)/VERSION.TXT Looks pretty standard to me, but maybe I'm wrong.
