Paste a whole text in one go. Structure it with these markers, each alone on its own line except the english markers:
# heading
The first heading after a part or chapter marker becomes its
title. A heading with no marker above it titles the text's
first chapter.
$ new chapter
$$$ new part
Use only for texts divided into parts. Numbering becomes
part.chapter.paragraph; without parts it is chapter.paragraph.
(blank line) ends a paragraph
+++ english +++
english translation
A +++ line (bare, or wrapping a label like "+++ english +++")
marks the block below it as the english of the paragraph
directly above. The block ends at the next blank line. It is
paired automatically and shown in the english boxes when you
edit that paragraph.
The title field names the text. The text number is assigned
automatically.
