Hive.sh

/home/hivetool/hive.sh is a bash script called by cron every 5 minutes that:

1. gets the hostname and date/time,
2. reads sensor calibration from config.conf (ver 0.5)
3. reads the hive sensors,
4. downloads the weather data in xml format from Weather Underground,
5. appends the data to a text file,
6. runs the graphing program /var/www/htdocs/graph_hive.pl,
7. uploads an xml file to the hivetool database.

/home/hivetool/hivetool.log is over written with messages each time hive.sh is run.
