+This directory contains the serialized ABI definitions for a typical build of
+the liburcu librairies. This information is extracted using libabigail
+(https://sourceware.org/libabigail/).
+
+The artefacts used to generate these were built with CFLAGS="-O0 -ggdb".
+
+You can compare the serialized ABI with a shared object to check for breaking
+changes. For example, here we compare an in-tree built version of
+liburcu-memb.so with the serialized ABI of stable-0.13 :
+
+  abidiff \
+    extras/abi/0.13/x86_64-pc-linux-gnu/liburcu-memb.so.7.xml \
+    src/.libs/liburcu-memb.so
