The prompt plugin has support for up to eight bars, shaded between up to three
colours depending on the information given to the plugin.  To give information
to the plugin you will need to have your prompt appearing in the prompt box
(not the main mud screen) and it will need to take the form:

optional text $46:245$ optional text $bleeding freely:perfect$ optional text

The bits inside the $ symbols is a fraction.  On some Merc derivatives you
could do:

  prompt $%h:%H$ $%m:%M$

Which would put your current health in the top bar and your current mana
level in the bottom bar.

The plugin also has support for standard Merc and Turfish health messages
appearing in the prompt (this isn't standard in Merc).  If %e gives the word
health of your opponent, then your prompt would be set like:

  prompt $%h:%H$ $%e:perfect$

Which would put your health in the top bar and your target's health in the
bottom bar.

Simple mathematical evaluation can be done too:

  prompt $=(%x%%1000):1000$>

This will show progress towards next level, assuming the next level
requires a static 1000 points.  Other muds (eg smaug) will require more
complex formulae, but can still be done.  It is necessary to type %% in order
to have the MUD return a simple % character in the prompt, which is used to
indicate modulus.

To tell the plugin to calculate the formula, prefix it with the = symbol.

Colours for fading may be set in the preferences window.
