# newsstat.pl version 0.3
 
 
 
###################################################################
# Collect statistics about the alt.os.linux.mandrake newsgroup.
# Check all articles in the last 7-day period. Rank posters by
# no. of posts and by volume of posts, report on top and bottom
# 20 posters. Show their name, no. posts, size of posts, percentage
# quoted lines. Rank user-agents used, by poster rather than by
# post. Rank top 10 threads. Rank top 10 cross-posted groups.
###################################################################
 
##################################################################
# RECENT CHANGES #
# 2004/06/19 - newsgroup name is $ARGV[0]
# - Allow command line flags for subtracting
# output if not pertinent for a group
# 2002/11/09 - Put Garry's writedata() function back in.
# - added "rn" to my list of UA's
# - Started using %distinct_agent for both User agent
# sections
# - named it newsstat.pl version 0.3
# 2002/11/06 - Fixed the earliest/latest file problem by using
# mtime rather than ctime, and simplifying the logic
# 2002/11/05 - moved user configurations to the top
# - fixed the cross-posting section
# - introduced the $newsgroup_name variable which
# later becomes $news$group
# - changed $name to $agent_name in countagents()
 
########### NEXT #############
# Commas in bottom section of report
# Show date the figures were compiled
# No. of HTML articles (Content-Type: text/html)
# No. of quoted sigs (/>\s*-- /)

# Count *all* User Agents that each poster uses
# What do we do about Bill Unruh's ] quote style?
# Change the way dates/times are checked
# include % share in posters by no. of arts
