o gh@sPdZdZddlmZmZmZGdddeZGdddeZGdd d eZ d S) a This package contains modules for standard tree transforms available to Docutils components. Tree transforms serve a variety of purposes: - To tie up certain syntax-specific "loose ends" that remain after the initial parsing of the input plaintext. These transforms are used to supplement a limited syntax. - To automate the internal linking of the document tree (hyperlink references, footnote references, etc.). - To extract useful information from the document tree. These transforms may be used to construct (for example) indexes and tables of contents. Each transform is an optional step that a Docutils component may choose to perform on the parsed document. reStructuredText) languagesApplicationError TransformSpecc@s eZdZdS)TransformErrorN)__name__ __module__ __qualname__r r Z/home/ubuntu/cloudmapper/venv/lib/python3.10/site-packages/docutils/transforms/__init__.pyrs rc@s(eZdZdZdZ dddZddZdS) Transformz; Docutils transform component abstract base class.
