Installation

Installing docutools as a non development dependency makes not much sense: The toolset is intended for generating documentation while/after developing.

Means: You want a Development Installation:

Add docutools = "^<version>" as a development dependency, e.g. within a pyproject.toml file.

Airtight Environment

("airtight"=no Internet access)

Configure the package server in your build framework (e.g. poetry like this).

Note

Some features do require CDN hosted javascript and CSS libs, pulled by the browsers of the readers - e.g. jquery.
