# Maria helper script
# Copies table' data and index file to other directory, or back, or compares.
# The other directory looks like a database directory, so that we can
# read copies from inside mysqld, that's also why we copy the frm.
# "mms" is a namespace for Maria_Make_Snapshot
# API:
# 1) set one of
# $mms_copy : to copy table from database to spare directory
# $mms_reverse : to copy it back
# $mms_compare : to compare both
# 2) set $mms_table_to_use to a number N: table will be mysqltest.tN
# 3) set $mms_purpose to say what this copy is for (influences the naming
# of the spare directory).
