## version.m4. ##
## ------------ ##
# - version.m4 needs to be updated only once, since it depends on
# configure.ac, not on the results of a 'configure' run.
# - It is guaranteed (with GNU Make) that when the version in configure.ac
# is changed, version.m4 is built only after the new version number is
# propagated to the Makefile. (Libtool uses the same guarantee.)
