# Test mysql_tzinfo_to_sql program against system zoneinfo files.
# The mysql_tzinfo_to_sql program loads the time zone tables in the mysql 
# database. It is used on systems that have a zoneinfo database (the set of 
# files describing time zones). 
# Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X. One 
# likely location for these files is the /usr/share/zoneinfo directory 
# (/usr/share/lib/zoneinfo on Solaris).
# The test is skipped if any of the required zoneinfo files cannot be found. 
# usage: 
# 1] mysql_tzinfo_to_sql tz_dir
# 2] mysql_tzinfo_to_sql tz_file tz_name
# 3] mysql_tzinfo_to_sql --leap tz_file
# Test aims loading zone tables in the mysql with above command.
# Data is loaded into zone table from test_zone database instead of mysql 
# database.
