 For example, here is the command to run the "alias" and "analyze" tests
 with an external server:
 
-mysql-test-run --extern alias analyze
+mysql-test-run --extern socket=/tmp/mysql.sock alias analyze
 
 To match your setup, you might also need to provide --socket, --user, and
 other relevant options.

scripts/convert-debug-for-diff.sh

+#!/usr/bin/perl -i
+#
+# This script converts all numbers that look like addresses or memory sizes,
+# in a debug files generated by --debug (like mysqld --debug), 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
