# 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.

#     pacman_version_major += 1
#     pacman_version_minor = 0
#     pacman_version_micro = 0

#   Real releases:
#     pacman_version_minor += 1
#     pacman_version_micro = 0
#
#   Bugfix releases:
#     pacman_version_micro += 1
#
#   pacman_version_suffix should be similar to one of the following:
#     For beta releases:          [beta2]
#     For code under development: [devel]
#     For production releases:    []
