# adam2 prompt theme
prompt_adam2_help () {
cat <<'EOF'
This prompt is color-theme-able. You can invoke it thus:
prompt adam2 [ simple ] <color1> <color2> <color3>
where the colors are for the hyphens, current directory, and user@host
bits respectively.
And you probably thought adam1 was overkill. If you've ever seen a
more complex prompt in your whole life, please e-mail it to me at
<adam@spiers.net>; I'd love to know that I'm not the saddest person
on the planet.
