    """parse release notes from commit messages into an output file

Given an output file and set of revisions, this command will parse commit
    messages for release notes then add them to the output file.

Release notes are defined in commit messages as ReStructuredText
    directives. These have the form::

.. directive:: title

content

Each ``directive`` maps to an output section in a generated release notes
    file, which itself is ReStructuredText. For example, the ``.. feature::``
    directive would map to a ``New Features`` section.

Release note directives can be either short-form or long-form. In short-
    form, ``title`` is omitted and the release note is rendered as a bullet
    list. In long form, a sub-section with the title ``title`` is added to the
    section.

The ``FILE`` argument controls the output file to write gathered release
    notes to. The format of the file is::

Section 1
       =========

...

Section 2
       =========

...

Only sections with defined release notes are emitted.

If a section only has short-form notes, it will consist of bullet list::

Section
       =======

* Release note 1
       * Release note 2

If a section has long-form notes, sub-sections will be emitted::

Section
       =======

Note 1 Title
       ------------

Description of the first long-form note.

Note 2 Title
       ------------

Description of the second long-form note.

If the ``FILE`` argument points to an existing file, that file will be
    parsed for release notes having the format that would be generated by this
    command. The notes from the processed commit messages will be *merged*
    into this parsed set.

During release notes merging:

* Duplicate items are automatically ignored
    * Items that are different are automatically ignored if the similarity is
      greater than a threshold.

This means that the release notes file can be updated independently from
    this command and changes should not be lost when running this command on
    that file. A particular use case for this is to tweak the wording of a
    release note after it has been added to the release notes file.

The -c/--check option checks the commit message for invalid admonitions.

The -l/--list option, presents the user with a list of existing available
    admonitions along with their title. This also includes the custom
    admonitions (if any).
