Revision:	1.14
Committed:	Fri Feb 16 09:13:12 2001 UTC (24 years, 10 months ago) by pjm2
Branch:	MAIN
CVS Tags:	HEAD
Changes since 1.13:	+2 -2 lines
State:	*FILE REMOVED*
Log Message:	After the radical changes in the i-scream database design, some of these classes had to be rewritten. The new design also meant that it was possible to generate multiple reports per machine per SQL select, so other parts of the DBReporter were rewritten to take advantage of this performance gain.
