-# Pixman versioning scheme
-#
-# - The version in git has an odd MICRO version number
-#
-# - Released versions both development and stable have an even MICRO
-# version number
-#
-# - Released development versions have an odd MINOR number
-#
-# - Released stable versions have an even MINOR number
-#
-# - Versions that break ABI must have a new MAJOR number
-#
-# - If you break the ABI, then at least this must be done:
-#
-# - increment MAJOR
-#
-# - In the first development release where you break ABI, find
-# all instances of "pixman-n" and change them to pixman-(n+1)
-#
-# This needs to be done at least in
-# configure.ac
-# all Makefile.am's
-# pixman-n.pc.in
-#
-# This ensures that binary incompatible versions can be installed
-# in parallel. See http://www106.pair.com/rhp/parallel.html for
-# more information
