# This script runs the sql statements in the folder, validates results, and tracks timings and other statistics.
#
# Notes:
# - Files containing the select statement are q0001.sql, q0002.sql, and so on.  This script only picks up the times beginning
#   with the fourth query in each file, then every third one thereafter so as to ignore the calgetstats(), calflushcache() times, 
#   etc.  Follow this pattern if adding more files query files.
#
# - A subdirectory will be created with the results.  The subdirectory name includes the date and the passed parm.  
#   For example, running the script such as "./go.sh nightly" on 7/1/09 will create a subdirectory named 20090701-nightly.

# - The log files contain output other query times that we don't want
