# Versioning rules ( C:R:A )
#
# 1. Start with version 0:0:0.
# 2. If any of the sources have changed, increment R. This is a new revision
#    of the current interface.
# 3. If the interface has changed, increment C and set R to 0. This is the
#    first revision of a new interface.
# 4. If the new interface is a superset of the previous interface
#    (that is, if the previous interface has not been broken by the
#    changes in this new release), increment A. This release is backwards
#    compatible with the previous release.
# 5. If the new interface has removed elements with respect to the
#    previous interface, then backward compatibility is broken; set A to 0.
#    This release has a new, but backwards incompatible interface.
#
# For more info see section 6.3 of the GNU Libtool Manual.
#
# In short;
# +1 : ? : +1  == new interface that does not break old one
# +1 : ? : 0   == new interface that breaks old one
#  ? : ? : 0   == no new interfaces, but breaks apps
#  ? :+1 : ?   == just some internal changes, nothing breaks but might work
#                 better
