+#
+# This script converts all numbers that look like addresses or memory sizes,
+# in a debug files generated by --debug (like mysqld --debug-dbug), to #.
+# The script also deletes all thread id's from the start of the line.
+
+# This allows you to easily compare the files (for example with diff)
+# to find out what changes between different executions.
+# This is extremely useful for comparing two mysqld versions to see
+# why things now work differently.
+
+# The script converts the files in place.
+#
+# Typical usage:
+#
+# convert-debug-for-diff /tmp/mysqld.trace /tmp/mysqld-old.trace
+# diff /tmp/mysqld.trace /tmp/mysqld-old.trace
