+dnl BURN_MICRO_VERSION is _not_ the third component Z of libburn-X.Y.Z
+dnl but an eternal counter which leads to SONAME. This misunderstanding
+dnl caused a messed up sequence of SONAMEs.
+dnl
+dnl SONAME and AGE describe the binary compatibility interval of a
+dnl dynamic library. See also http://www.gnu.org/software/libtool/manual.html
+dnl
+dnl The name of the library will be libburn.so.$SONAME.$REV.$AGE
+dnl In the terminology of this file:
+dnl   SONAME= LT_CURRENT
+dnl   REV   = LT_REVISION
+dnle  AGE   = LT_AGE
+dnl
+dnl In the past the following SONAMEs of libburn have been released.
+dnl All with AGE=0.
+dnl  0.2.2 = 2 , 0.2.3 = 3 , 0.2.6 = 6
+dnl  0.3.0 = 0 , 0.3.2 = 2 , 0.3.4 = 4 . 0.3.6 = 6 , 0.3.8 = 4
+dnl  0.4.0 = 4
+dnl 
+dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
+dnl   SONAME=10, REV=1, AGE=6
+dnl This rectification declared the current version
+dnl to be binary compatible down to libburn-0.3.4.
+dnl Real backward compatibility is given down to libburn-0.3.2.
+dnl Beware of libburn-0.2.6 which had SONAME=6.
+dnl
+dnl SONAME=10, REV=0, AGE=6 would be appropriate for libburn-0.4.0
+dnl but was not issued, regreattably.
+dnl
+dnl If libburn-0.4.0 gets patched, its SONAME will become 10, AGE 6, and
+dnl REV will be set to one higher than the highest REV of SONAME 10.
+dnl If libburn-0.4.1 is still on SONAME 10 then its REV gets set one higher
+dnl than that.
+dnl As soon as 0.4.1 becomes upwardly incompatible, it shall become 11,0,7.
+dnl From then on it counts REV independently of libburn-0.4.0.
+dnl Whether 0.4.1 alters independent REV at all, is not decided yet.
+dnl It may well stay 0 until a release version joins SONAME 11.
+dnl
+dnl Under the preconditions
+dnl   SONAME= $BURN_MICRO_VERSION - $BURN_INTERFACE_AGE
+dnl   REV=    $BURN_INTERFACE_AGE
+dnl   AGE=    $BURN_BINARY_AGE
+dnl the following old instructions were reasonable. Their drawback
+dnl is that they cause large jumps in SONAME, when BURN_INTERFACE_AGE gets
+dnl reset to 0 from a high value. So this is outdated now:
