+# BUG#42941: --database parameter to mysqlbinlog fails with RBR
+#
+# WHAT
+# ====
+#
+#  This test aims at checking whether a rows log event is printed or
+#  not when --database parameter is used to filter events from one
+#  given database.
+#
+# HOW
+# ===
+#
+#  The test is implemented as follows: 
+#
+#    i) Some operations are done in two different databases:
+#       'test' and 'b42941';
+#   ii) mysqlbinlog is used to dump the contents of the binlog file
+#       filtering only events from 'b42941'. The result of the dump is
+#       stored in a temporary file. (This is done with and without
+#       --verbose/hexdump flag);
+#  iii) The contents of the dump are loaded into a session variable;
+#   iv) The variable contents are searched for 'test' and 'b42941';
+#    v) Should 'test' be found, an ERROR is reported. Should 'b42941' be
+#       absent, an ERROR is reported.
