+- Aliases to `mpris1`
+- Requires [dbus-core] and [text] packages.
+ To activate, pass `--flags="with_mpris"` during compilation.
+- PlayerName: player supporting MPRIS v1 protocol, in lowercase.
+- Args: default monitor arguments.
+- Variables that can be used with the `-t`/`--template` argument:
+ `album`, `artist`, `arturl`, `length`, `title`, `tracknumber`
+- Default template: `<artist> - <title>`
+- Example:

+ Run Mpris1 "clementine" ["-t",
