-s This option allows shell commands to be typed in to mprompt, to be run by whatever user it is running
as. (Typically root if it is run from /etc/inittab).
To enter a shell command, type a "!", followed by the command to run, followed by Enter.
-m key=key
This option allows remapping keys. Any key can be remapped to any other key, which is useful to
support keyboard with unusual key layouts, or missing keys.
For alphanumeric and punctuation keys, individual symbols can be remapped. For example, "-m a=b"
will turn each entered "a" into "b".
For other keys, use the following names:
<return>
<tab>
<space>
<up>
<down>
<left>
<right>
<backspace>
For example, -m "n=<down>" will map the "n" key to the down arrow, causing that key to change to the
next track; -m "<space>=<return>" will make the space bar act as a pause.
It's possible to swap keys too. For example, -m "<down>=<up>" -m "<up>=<down>"
A single key can also be bound to a series of keystrokes. For example, -m "1=Mule Variations<return>"
will cause the "1" key to play the "Mule Variations" album, a nice choice.
-t n
Adds a timeout, a specified number of seconds after which the entry on the command line will be
cleared. Useful for headless systems, to avoid cat-on-keyboard confusing your later commands.
-T Enables terse output mode. This mode tries to avoid displaying excessive or complex things, with the
intent that mprompt's output can be piped into a speech synthesiser, such as espeak.
