+this is a stupid program that lets you turn telegram message links
+into BBcode suitable for pasting on somethingawful dot com
 
-    println!("{}", to_bbcode(&link, &msg).unwrap());
+you can use it by putting a valid telegram message link in the url and
+waiting a few seconds (yes it's currently slow, yes it's SA's fault,
+yes I could work around but can't be bothered atm)
+
+for example:
+
+  https://tgsa.tazj.in/https://t.me/RWApodcast/113
+
+yes, that looks stupid, but it works

+if you see this message and think you did the above correctly, you
+didn't. try again. idiot.
