+
+=head1 SYNOPSIS
+
+hit-frequencies [options] <spam-log> <ham-log>
+
+ Options:
+ -c,--cffile=path Use path as the rules directory
+ -s,--scoreset=n Use scoreset n
+ -f,--falses Count only false-positives/false-negatives
+ -a,--all Report all tests (including subrules)
+ -p,--percentages Report percentages instead of raw hits (implies -x)
+ -x,--extended "Extended" output, include RANK, S/O and SCORE
+ -m,--matchrules=re Print rules matching the regular expression
+ -t,--tflags=re Print only rules with tflags matching the regular expression
+ -M,--matchlogs=re Consider only logs matching the regular expression
+ -X,--excludelogs=re Exclude logs matching this regular expression
+ -L,--onlylanguage=lc Only print language specific tests for specified lang code (try 'all')
+ -l,--alsolanguage=lc Also print language specific tests for specified lang code (try 'all')
+ -i,--ig Use IG (information gain) for ranking
+ -T,--times Display rule times (implies -x, -p)
+ -o,--overlaps Display hit overlaps against all other rules
+ -S,--scoremap Display score-map of hits
+ -P,--promotion Flag rules that meet the promotion criteria
+ -d,--XML XML output (conflicts with -x, -p)
+
+=head1 DESCRIPTION
+
+B<hit-frequencies> will read the mass-check logs F<spam.log> and
+F<ham.log> or the logs given on the command line. The output will
+contain a summary of the number of ham and spam messages and detailed
+statistics for each rule. The output will include the following
+columns:
+
+=over 4
+
+=item OVERALL
+
+Number of times (or percentage with B<-p>) the rule hit on
+all messages (spam or ham).
+
+=item SPAM
+
+Number of times (or percentage with B<-p>) the rule hit on
+spam messages.
+
+=item HAM
+
+Number of times (or percentage with B<-p>) the rule hit on
+ham messages.
+
+=item FPOS
+
+=item FNEG
+
+Shown only with B<-f>, these refer to the number of times (or
+percentage) the rule hit on messages that were found to be false
+positives or false negatives.
+

- -s SC which scoreset to use

+Shown only with B<-x> or B<-p>, this is the number of spam hits
+divided by total number of hits (C<S/O> refers to spam divided by
+overall).
- if either the spam or and ham logs are unspecified, the defaults
- are \"spam.log\" and \"ham.log\" in the cwd.
+=item RANK
-";
+Shown only with B<-x> or B<-p>, and when B<-i> is not used, this is a
+measure that attempts to indicate how I<good> or I<useful> a test
+is. The higher it is, the better the test.
+
+=item IG
+
+Shown only with B<-i>, this is another measure that attempts to
+indicate how I<useful> a test is.
+
+=item SCORE
+
+Shown only with B<-x> or B<-p>, this is the current score assigned to
+the rule.
+
+=item NAME
+
+This is the rule's name.
