# Props to Denis Roy (webmaster@eclipse.org) for the basecode from which this script grew.
# Logic, DB and Presentation lumped here for simplicity.
# Please avoid using aggregate functions (COUNT, SUM, MAX, MIN, etc) on busy web pages.
# For bugzilla this is not critical as the tables are small (<10,000,000 records)
# but imagine if every project displays a COUNT(*) for their project's bugs right on the front page!
# ** NOTE ** You need to tell the WebMaster from which URL you are loading this class from, 
# otherwise the connect() will fail.
   
# Load up the classfile
