+#
+# The following steps are followed in the rule below
+#
+# 1) Generate preprocessor output for the files that need to
+#    be tested for abi/api changes. use -nostdinc to prevent 
+#    generation of preprocessor output for system headers. This 
+#    results in messages in stderr saying that these headers 
+#    were not found. Redirect the stderr output to /dev/null 
+#    to prevent seeing these messages.
+# 2) sed the output to remove blank lines and lines that begin
+#    with # (The header information is retained to enable easy
+#    analysis of abi diffs at a later stage).
+# 3) diff the generated file and the canons (.pp files already in
+#    the repository).
+# 4) delete the .out file that is generated.
+#
+# If the diff fails, the generated file is not removed. This will
+# be useful for analysis of ABI differences (e.g. using a visual
+# diff tool).
+#
+# A ABI change that causes a build to fail will always be accompanied
+# by new canons (.out files). The .out files that are not removed will
+# be replaced as the new .pp files.
+#
+# e.g. If include/mysql/plugin.h has an ABI change then this rule would
+# leave a include/mysql/plugin.out file.
+#
+# A developer with a justified API change will then do a
+# mv include/mysql/plugin.out include/mysql/plugin.pp 
+# to replace the old canons with the new ones.
