+    Groove on Demand will stream audio to web clients in the native format of your source media files, but for maximum
+    portability, performance, and interoperability with reverse proxies, it's a good idea to transcode to .webm first.
+    Use the [b]transcode[/b] command to cache transcoded copies of every track currently in a playlist that isn't
+    already in .webm format. Existing cache entries will be skipped. See also [b]cache[/b].
