/*
* Example of a report-writing program that searches the ASL
* data store for messages.
*
* This program used the ASL search API to find messages logged by the
* "SampleD". The user may specify a maximum log priority
* and a time interval as command line options.
*
* usage: report [-l max_level] [-s start_offset] [-e end offset]
* max level must be an integer in the range 0 to 7.
* start_offset and end_offset are integers that denote a number
* of hours before the time at which the program is run.
*
* For example, to get a report of all log messages of level 4 (Warning)
* or less, in the interval beginning 12 hours ago and ending 6 hours ago:
*
* report -l 4 -s 12 -e 6
*
* The default for max_level is 5 (Notice).
* The default start time is 1 hours ago.
* The default end time is the current time.
