# ============================================================================
#
# Test of mysqltest itself
#
# There are three rules that determines what belong to each command
# 1. A normal command is delimited by the <delimiter> which by default is
#    set to ';'
#
#   ex: | select *
#       |   from t1;
#       |
#   Command: "select * from t1"
#
# 2. Special case is a line that starts with "--", this is a comment
#    ended when the new line character is reached. But the first word
#    in the comment may contain a valid command, which then will be
#    executed. This can be useful when sending commands that
#    contains <delimiter>
#
# 3. Special case is also a line that starts with '#' which is treated
#     as a comment and will be ended by new line character
#
