# Generic colour fade-bar prompt theme from bashprompt

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

  prompt fade [8bit] [<fade-bar-and-cwd> [<userhost> [<date>]]] 

where the parameters are the colors for the fade-bar and current
working directory, user@host text, and date text respectively.  The
default colors are green, white, and white.  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.
