# mysqldump.inc
#
# SUMMARY: include file to facilitate testing the quality of mysqldump output
#
# INPUTS:  Two variables:
#          $table_name - the name of the table that was dumped
#          $mysqldumpfile - the name of the file that captured mysqldump output
#
# OUTPUTS: minor echo data:
#          We 'echo' some stage information to the .result file:
#          'altering original table', 'restoring from dumpfile', 'comparing'
#
# OTHER FILES:  We use include/diff_tables.inc to compare the original, renamed
#               table with the 'restored' one. 
#
# DESCRIPTION: This file works by being fed the name of the original table
#              and a mysqldump output file.  The original table is then renamed
#              to <table_name>_orig, the mysqldump file is used to recreate the
#              table, then diff_tables.inc is called to compare them.
#
# LIMITATIONS:  Does *NOT* work with xml output!
