This prompt is color-scheme-able.  You can invoke it thus:

  prompt bigfade [<fade-bar> [<userhost> [<date> [<cwd>]]]]

where the parameters are the colors for the fade-bar, user@host text,
date text, and current working directory respectively.  The default
colors are blue, white, white, and yellow.  This theme works best with
a dark background.


Recommended fonts for this theme: either UTF-8, or nexus or vga or similar.
If you don't have any of these, the 8-bit characters will probably look
stupid.
