auto's main use it to automate the release process for your project This can be broken down into three core steps:
pre: (optional) Check if new version
1. Generate CHANGELOG.md
2. Publish code
3. Generate github release notes
auto makes no assumptions about your publishing process. Each tool is a function that can be run in isolation and only does one thing really well. For instance, you could just use auto changelog to generate the changelog and nothing else or use auto version to calculate just the semver bump.
