Problem Description

There is currently no means by which a user can add their own custom conversion methods. In order to add functionality, they need to edit the BookPub source code itself.

Users need a way to add the conversions they need to fit their own publishing needs.

Proposed Solution

Add a folder "plugins" in the root of new bookpub projects where users can add their own cusotm conversion functions.

Plugins modules should include:

• a variable for the manuscript content
• a variable for options
• a convention for adding plugin options in the book.config.yml file

Alternatives Considered

Initially considered adding remark-directives and creating a folder called directives in the user's book project root. But it seemed a better option not to limit users to directives and unified only. They should be able to add any functionality they want, even if it is something outside the unified ecosystem.
