Here is the complete, sample client file:

    require 'statistician'

    class Defense < Statistician::Reportable
      rule "[The ]<name> wounds you[ with <attack>] for <amount>
point[s] of <kind>[ damage]."
      rule "You are wounded for <amount> point[s] of <kind> damage."
    end

    class Offense < Statistician::Reportable
      rule "You wound[ the] <name>[ with <attack>] for <amount>
point[s] of <kind>[ damage]."
      rule "You reflect <amount> point[s] of <kind> damage to[ the]
<name>."
    end

    class Defeat < Statistician::Reportable
      rule "You succumb to your wounds."
    end

    class Victory < Statistician::Reportable
      rule "Your mighty blow defeated[ the] <name>."
    end

    class Healing < Statistician::Reportable
      rule "You heal <amount> points of your wounds."
      rule "<player> heals you for <amount> of wound damagepoints."
    end

    class Regen < Statistician::Reportable
      rule "You heal yourself for <amount> Power points."
      rule "<player> heals you for <amount> Power points."
    end

    class Comment < Statistician::Reportable
      rule "### <comment> ###"
    end

    class Ignored < Statistician::Reportable
      rule "<player> defeated[ the] <name>."
      rule "<player> has succumbed to his wounds."
      rule "You have spotted a creature attempting to move stealthily
about."
      rule "You sense that a creature is nearby but hidden from your
sight."
      rule "[The ]<name> incapacitated you."
    end


    if __FILE__ == $0
      lotro = Statistician::Reporter.new(Defense, Offense, Defeat,
Victory,
                                         Healing, Regen, Comment,
Ignored)
      lotro.parse(File.read(ARGV[0]))

      num = Offense.records.size
      dmg = Offense.records.inject(0) { |sum, off| sum +
Integer(off.amount.gsub(',', '_')) }
      d = Defense.records[3]

      puts <<-EOT
    Number of Offense records: #{num}
    Total damage inflicted: #{dmg}
    Average damage per Offense: #{(100.0 * dmg / num).round / 100.0}

    Defense record 3 indicates that a #{d.name} attacked me
    using #{d.attack}, doing #{d.amount} points of damage.

    Unmatched rules:
    #{lotro.unmatched.join("\n")}

    Comments:
    #{Comment.records.map { |c| c.comment }.join("\n")}

      EOT
    end

And here is the output it generates, using the [hunter.txt][1] data
file:

    Number of Offense records: 1300
    Total damage inflicted: 127995
    Average damage per Offense: 98.46

    Defense record 3 indicates that a Tempest Warg attacked me
    using Melee Double, doing 108 points of damage.

    Unmatched rules:
    The Trap wounds Goblin-town Guard for 128 points of Common damage.
    Nothing to cure.
