//! Convert one PDF page to SVG on stdout, with its rasterized-region report
//! on stderr.
//!
//! ```text
//! cargo run -p pdfrum-svg --example convert -- file.pdf [page] > page.svg
//! ```
//!
//! The smallest thing that exercises the whole crate end to end, and the way
//! to look at what a document actually converts to rather than at a score.

// Through the facade alone, which is the shortest path a caller has: the
// `svg-export` feature puts `Page::to_svg` on the facade's own page type, so nothing
// here names an engine crate.
