    """histogram of changes to the repository

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

# display count of lines changed in a time range
      hg churn -d "2020-04 to 2020-09"

It is possible to map alternate email addresses to a main address
    by providing a file using the following format::

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 "=".
