# This file is almost identical in functionality to
# ompi_get_version.m4.  It is unfortunate that we have to duplicate
# code, but it is really the only what that I can think to do it.  :-(
# Hence, if you change the logic here for determining version numbers,
# YOU MUST ALSO CHANGE IT IN ompi_get_version.m4!!
