# mysqldump_restore.test
#
# Purpose:  Tests if mysqldump output can be used to successfully restore
#           tables and data.  
#           We CREATE a table, mysqldump it to a file, ALTER the original
#           table's name, recreate the table from the mysqldump file, then
#           utilize include/diff_tables to compare the original and recreated
#           tables.
#
#           We use several examples from mysqldump.test here and include
#           the relevant bug numbers and headers from that test.
#
# NOTE:     This test is not currently complete and offers only basic
#           cases of mysqldump output being restored. 
#           Also, does NOT work with -X (xml) output!
