dnl Versioning scheme shamelessly copied from libexif.
dnl Short walkthrough. C means CURRENT, A mean AGE, R means REVISION
dnl 1) When you make a change that breaks binary compatibility, increment CURRENT, reset REVISION to 0 and:
dnl   1.1) If the change doesn't remove interfaces, increment AGE, otherwise reset to 0.
dnl 2) When you make just a source change that doesn't break binary compatibility, increment REVISION.
dnl When you make a change that adds features, increment AGE, and set REVISION to 0
dnl C:A:R
dnl 10:0:0   Version 0.1.0
dnl 11:0:0   Version 0.1.1: four more fields to cpu_raw_data_t
dnl 11:0:1   Version 0.1.2: added cpu_msr* functions
dnl 11:0:2   Version 0.1.3: added cpu_clock_by_ic() function
dnl 11:0:3   Version 0.1.4: just an identification change, to reflect the detection table upgrades
dnl 12:1:0   Version 0.2.0: two more fields to cpu_id_t
dnl 12:1:1   Version 0.2.1: more processors support
