# UPDATING VERSION NUMBERS FOR RELEASES
#
# libalpm:
# current
# The most recent interface number that this library implements.
# revision
# The implementation number of the current interface.
# age
# The difference between the newest and oldest interfaces that this library
# implements. In other words, the library implements all the interface
# numbers in the range from number current - age to current.
#
# 1. Start with version information of `0:0:0' for each libtool library.
# 2. Update the version information only immediately before a public release of
# your software. More frequent updates are unnecessary, and only guarantee
# that the current interface number gets larger faster.
# 3. If the library source code has changed at all since the last update, then
# increment revision (`c:r:a' becomes `c:r+1:a').
# 4. If any interfaces have been added, removed, or changed since the last
# update, increment current, and set revision to 0.
# 5. If any interfaces have been added since the last public release, then
# increment age.
# 6. If any interfaces have been removed since the last public release, then
# set age to 0.
