Cli

This library provides the changelog command to normalize the changelog format. It reads the CHANGELOG.md file and override it with the new format:

changelog

To use other file name:

changelog --file=History.md

To generate an empty new CHANGELOG.md file:

changelog --init

Available options:

Option	Description
--file	The markdown file of the changelog. The default value is CHANGELOG.md.
--url	The base url used to build the diff urls of the different releases. It is taken from the existing diff urls in the markdown. If no urls are found, try to catch it using the url of the git remote repository.
--https	Set to false to use http instead https in the url (--https=false).
--init	Init a new empty changelog file.
