+This example demonstrates how to use Serde with Syntex. On stable or nightly
+with Syntex, it can be built with:
+
+```
+% multirust run stable cargo run
+     Running `target/debug/serde-syntex-example`
+{"x":1,"y":2}
+Point { x: 1, y: 2 }
+
+% multirust run nightly cargo run
+     Running `target/debug/serde-syntex-example`
+{"x":1,"y":2}
+Point { x: 1, y: 2 }
+```
+
+On nightly, it can use a plugin with:
+
+```
+% multirust run nightly cargo run --features nightly --no-default-features
+```
