# Before making a release, the LT_VERSION string should be modified.
# The string is of the form C:R:A.
# - 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
