+Rust hexchat-plugin
+===================
+
+`hexchat-plugin` provides safe and rusty API bindings for developing native HexChat plugins.
+
+Example plugin:
+
+```rust
+#[macro_use]
+extern crate hexchat_plugin;
+
+use hexchat_plugin::{Plugin, PluginHandle, InfoId};
+
+use std::sync::Mutex;
+use std::sync::Arc;
+
+#[derive(Default)]
+struct MyPlug {
+    // be careful with these: we don't want to move them into the hooks, as that would cause memory leaks!
+    // we can safely use Arc::downgrade on them, however!
+    cmutex: Arc<Mutex<Vec<hexchat_plugin::CommandHookHandle>>>,
+    smutex: Arc<Mutex<Vec<hexchat_plugin::ServerHookHandle>>>,
+    pmutex: Arc<Mutex<Vec<hexchat_plugin::PrintHookHandle>>>,
+    tmutex: Arc<Mutex<Vec<hexchat_plugin::TimerHookHandle>>>,
+}
+
+
+impl Plugin for MyPlug {
+    fn init(&self, ph: &mut PluginHandle, _arg: Option<&str>) -> bool {
+        ph.register("MyPlug", "Prints the old topic on topic change", "0.1.0");
+        ph.print("Loaded MyPlug 0.1.0");
+
+        let enabled = Arc::new(Mutex::new(false));
+        {
+            let flag = enabled.clone();
+            self.pmutex.lock().unwrap().push(ph.hook_print("Topic Change", move |ph, _word| {
+                if *flag.lock().unwrap() {
+                    if let Some(topic) = ph.get_info(&InfoId::Topic) {
+                        ph.print(&format!("\x0322*\t\x0329Previous topic:\x03 {}", topic));
+                    }
+                }
+                hexchat_plugin::EAT_NONE
+            }, hexchat_plugin::PRI_NORM));
+        }
+
+        self.cmutex.lock().unwrap().push(ph.hook_command("PrintOldTopic", move |ph, _word, word_eol| {
+            match word_eol.get(1) {
+                Option::Some(&s) if s == "true" => {
+                    ph.print("Set PrintOldTopic to true");
+                    *enabled.lock().unwrap() = true;
+                }
+                Option::Some(&s) if s == "false" => {
+                    ph.print("Set PrintOldTopic to false");
+                    *enabled.lock().unwrap() = false;
+                }
+                Option::Some(_) => {
+                    ph.print("Usage: /PrintOldTopic [true|false]");
+                }
+                Option::None => {
+                    ph.print(&format!("PrintOldTopic: {}", *enabled.lock().unwrap()));
+                }
+            }
+            hexchat_plugin::EAT_ALL
+        }, hexchat_plugin::PRI_NORM, Some("Usage: /PrintOldTopic [true|false]")));
+        true // tells hexchat we have successfully initialized
+    }
+}
+
+hexchat_plugin!(MyPlug);
