# Generic colour fade-bar prompt theme from bashprompt
# Created by Jim Foltz <aa204@acorn.net>
# Changed by Spidey 08/06
# Converted to zsh prompt theme by <adam@spiers.net>
prompt_fade_help () {
cat <<EOH
This prompt is color-scheme-able. You can invoke it thus:
prompt fade [<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.
