# Before making a release, the LTVERSION string should be modified.
# The string is of the form CURRENT:REVISION:AGE.
#
# CURRENT (C)
#	The most recent interface number that this library implements.
#
# REVISION (R)
#	The implementation number that this library implements.
#
# AGE (A)
#	The difference between the newest and oldest interfaces that this
#	library implements. In other works, the library implements all the
#	interface numbers in the range from number 'CURRENT - AGE' to
#	'CURRENT'.
#
# This means that:
#
#   - If interfaces have been changed or added, but binary compatibility has
#     been preserved, change to C+1:0:A+1
#
#   - If binary compatibility has been broken (eg removed or changed
#     interfaces) change to C+1:0:0
#
#   - If the interface is the same as the previous version, change to C:R+1:A
