AC_PREREQ([2.57])

#   hsakmt versioning scheme
#
#   - The version in git has an odd MICRO version number
#
#   - Released versions, have an even MICRO version 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 "hsakmt-n" and change them to hsakmt-(n+1)
#
#          This needs to be done at least in 
#                    configure.ac
#                    all Makefile.am's
#                    hsakmt-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
