//! Paste into a page: the path Ctrl+V takes through the chrome.
 //!
 //! `editing_action_cmd(Paste)` is what `main.rs` calls, so this exercises the
 //! real route — WebKit's Paste command reads through `WPEClipboard::read`,
 //! which is only there if the display vends a clipboard at all.
 //!
 //! Needs a Wayland display for wl-paste, so run it inside a session:
 //!   cce-shadow --instance <n> run ./target/release/examples/wpe_paste <url>
