+# 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:
+# Extreme huge major changes:
+# 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: []
