# The soversion number needs to match that generated by libtool.  The following
# lines should read configure.ac to get the current interface number and
# subtract it from the interface age, to get the oldest interface number
# supported by the library. This should correspond to the soversion assigned
# to the library by libtool.  (This isn't documented, and is system dependent,
# so we need to check it doesn't break with future versions of libtool.)
