Document-to-markdown transformer using pandoc.
Converts EPUB, DOCX, HTML, RTF, FB2, RST, and LaTeX inputs into a
GitHub-flavored Markdown variant (text/markdown).
Pandoc auto-detects the input format from the file extension. The
variant pipeline writes the input to a temp file with the original
extension preserved, so detection works without an explicit -f flag.
Embedded images are not extracted — image references in the output
point to the original archive's internal paths and will be broken
links. Use a separate image previewer (e.g. Epub.EpubThumbnailer) for
cover art.
