# Shows statistics about recent agents that have tested with iExploder. 
# It takes all or part of an apache logfile via stdin, and outputs a list
# of all the agents who tested within that section, what their last test
# was, and how many tests they have done.

# The usefulness is finding out where a browser crashed.
