+## Format
+##
+## ACTION: [AUDIENCE:] COMMIT_MSG
+##
+## Description
+##
+## ACTION is one of 'chg', 'fix', 'new', 'rem', 'sec'
+##
+## Is WHAT the change is about.
+##
+## 'chg' is for refactor, small improvement, cosmetic changes...
+## 'fix' is for bug fixes
+## 'new' is for new features, big improvement
+## 'rem' is for removed features
+## 'sec' is for security fixes
+##
+## Each MR title should have exactly one ACTION, and no non-merge commits should have these.
+##
+## AUDIENCE is optional and can be 'dev', 'usr', 'pkg', 'test', 'doc'
+##
+## Is WHO is concerned by the change.
+##
+## Included in release notes and changelog:
+## 'usr' is for final users
+## 'pkg' is for packagers
+##
+## Included in changelog:
+## 'dev' is for developers
+##
+## Omitted from changelog:
+## 'test' is for test-only changes
+## 'doc' is for doc-only changes
+##
+## COMMIT_MSG is ... well ... the commit message itself.
+##
+##
+## Examples:
+##
+## If you want to add a release note, mark it for usr or pkg audience:
+##
+## sec: usr: Fix CVE-YYYY-NNNN
+## rem: usr: Deprecate feature xyz
+## new: pkg: libngtcp2 is now required
+##
+## If you want to mention it just in the changelog, add dev audience:
+##
+## chg: dev: Refactor xyz
+## fix: dev: Fix a rare edge case of xyz
+## new: dev: Add new QTYPE
+##
+## If you don't specify audience context, or use a custom one, it won't end
+## up in the changelog:
+##
+## chg: doc: Tidy up the docs
+## fix: test: Fix a broken test
+## chg: Do some cleanup
+## sec: test: Add a test case for CVE-YYYY-NNNN
+##
+## Please note that multi-line commit messages are supported; only the first
+## line will be considered as the "summary" of the commit message. So tags
+## and other rules only apply to the summary. The body of the commit
+## message will be displayed in the changelog without reformatting.

+##
+## Please note that ``section_regexps`` will only classify commits and won't
+## make any changes to the contents. So you'll probably want to go check
+## ``subject_process`` (or ``body_process``) to do some changes to the subject,

+##
+## - ReSub(pattern, replacement): will apply regexp substitution.
+##
+## - Indent(chars=" "): will indent the text with the prefix
+## Please remember that template engines gets also to modify the text and
+## will usually indent themselves the text if needed.
+##
+## - Wrap(regexp=r"\n\n"): re-wrap text in separate paragraph to fill 80-Columns
+##
+## - noop: do nothing
+##
+## - ucfirst: ensure the first letter is uppercase.
+## (usually used in the ``subject_process`` pipeline)
+##
+## - final_dot: ensure text finishes with a dot
+## (usually used in the ``subject_process`` pipeline)
+##
+## - strip: remove any spaces before or after the content of the string
+##
+## - SetIfEmpty(msg="No commit message."): will set the text to
+## whatever given ``msg`` if the current text is empty.

+## - mustache(<template_name>)
+##
+## Template name could be any of the available templates in

+## - mustache("markdown")
+## - mustache("restructuredtext")
+##
+## - makotemplate(<template_name>)
+##
+## Template name could be any of the available templates in

+## This option tells gitchangelog what encoding is outputed by ``git log``.
+## The default is to be clever about it: it checks ``git config`` for

+
+
+## ``publish`` is a callable
+##
+## Sets what ``gitchangelog`` should do with the output generated by

+##
+## Some helper callable are provided:
+##
+## Available choices are:
+##
+## - stdout
+##
+## Outputs directly to standard output
+## (This is the default)
+##
+## - FileInsertAtFirstRegexMatch(file, pattern, idx=lamda m: m.start())
+##
+## Creates a callable that will parse given file for the given
+## regex pattern and will insert the output in the file.
+## ``idx`` is a callable that receive the matching object and
+## must return a integer index point where to insert the
+## the output in the file. Default is to return the position of
+## the start of the matched string.
+##
+## - FileRegexSubst(file, pattern, replace, flags)
+##
+## Apply a replace inplace in the given file. Your regex pattern must
+## take care of everything and might be more complex. Check the README
+## for a complete copy-pastable example.

+
+## ``revs`` is a list of callable or a list of string
+##
+## callable will be called to resolve as strings and allow dynamical
+## computation of these. The result will be used as revisions for
+## gitchangelog (as if directly stated on the command line). This allows
+## to filter exaclty which commits will be read by gitchangelog.
+##
+## To get a full documentation on the format of these strings, please
+## refer to the ``git rev-list`` arguments. There are many examples.
+##
+## Using callables is especially useful, for instance, if you
+## are using gitchangelog to generate incrementally your changelog.
+##
+## Some helpers are provided, you can use them::
+##
+## - FileFirstRegexMatch(file, pattern): will return a callable that will
+## return the first string match for the given pattern in the given file.
+## If you use named sub-patterns in your regex pattern, it'll output only
+## the string matching the regex pattern named "rev".
+##
+## - Caret(rev): will return the rev prefixed by a "^", which is a
+## way to remove the given revision and all its ancestor.
+##
+## Please note that if you provide a rev-list on the command line, it'll
+## replace this value (which will then be ignored).
+##
+## If empty, then ``gitchangelog`` will act as it had to generate a full
+## changelog.
+##
+## The default is to use all commits to make the changelog.
