It rebuilds the Xymon web pages to the look they had
at a particular point in time, based upon the historical information
logged about events.
snapshot.cgi is passed a QUERY_STRING environment variable with the
mon (Start month of the snapshot)
day (Start day-of-month of the snapshot)
yr (Start year of the snapshot)
hour (Start hour of the snapshot)
min (Start minute of the snapshot)
sec (Start second of the snapshot)
The "month" parameters must be specified as the three-letter
english month name abbreviation: Jan, Feb, Mar ...
"day" must be in the range 1..31; "yr" must be specified
including century (e.g. "2003"). "hour" must be specified
using a 24-hour clock.
All of the processing involved in generating the report is done
xymongen(1) with the proper "--snapshot" option.
