+#  
+#  Description 
+#  ===========
+#
+#  This test case covers Requirements for replication using different
+#  combinations of indexes and blob fields. 
+#
+#  It acts as a complement for rpl_row_img_sanity tests as it checks
+#  that in a chained replication scenario, replication does not break.
+#
+#  Usage
+#  =====
+#
+#  Before including this file the following variables should be set:
+#    * $server_1_engine
+#    * $server_2_engine
+#    * $server_3_engine
+#
+#  Example:
+#
+#     -- let $server_1_engine= Falcon
+#     -- let $server_2_engine= MyISAM
+#     -- let $server_3_engine= InnoDB
+#
+#     -- source extra/rpl_tests/rpl_row_img_blobs.test
+#

+  # The comments below (on create table) must be read with the SQL
+  # instructions issued later in mind. Declaring a table obviously is 
+  # not enough to assert anything.
+  #
+  # Also, the tests in this file make more sense when performed with
+  # binlog_row_image configured as NOBLOB.
