     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.
     Aliases will be split from the rightmost "=".
