+With kernel inotify support, output is triggered by file changes

Otherwise, @command{tail} sleeps for one second between checks---
use @option{--sleep-interval=@var{n}} to change that default---which can
make the output appear slightly less responsive or bursty.
+When using tail without inotify support, you can make it more responsive
+by using a sub-second sleep interval, e.g., via an alias like this:
