1	//! Writes a `.pptx` from a Markdown file, so an external reader can be asked what it makes of it.
2	//!
3	//! A deck is the format where a self-consistent test proves least, because the whole of the risk is
4	//! the SKELETON: a slide points at a layout, a layout at a master, a master at a theme, and a file
5	//! with any link missing opens with a repair prompt rather than an error. Nothing this crate's own
6	//! reader does would notice.
7	//!
8	//! ```text
9	//! cargo run -p oxedyne_fe2o3_file --example make_pptx -- in.md out.pptx
10	//! soffice --headless --convert-to pdf out.pptx
