+
+ This command will display a histogram representing the number
+ of changed lines or revisions, grouped according to the given
+ template. The default template will group changes by author.
+ The --dateformat option may be used to group the results by
+ date instead.
+
+ Statistics are based on the number of changed lines, or
+ alternatively the number of matching revisions if the
+ --changesets option is specified.
+
+ Examples::
+
+ # display count of changed lines for every committer
+ hg churn -t '{author|email}'
+
+ # display daily activity graph
+ hg churn -f '%H' -s -c
+
+ # display activity of developers by month
+ hg churn -f '%Y-%m' -s -c
+
+ # display count of lines changed in every year
+ hg churn -f '%Y' -s
+
+ It is possible to map alternate email addresses to a main address
+ by providing a file using the following format::
+
+ <alias email> = <actual email>
+
+ Such a file may be specified with the --aliases option, otherwise
+ a .hgchurn file will be looked for in the working directory root.
