# adam2 prompt theme
prompt_adam2_help () {
cat <<'EOF'
This prompt is color-scheme-able. You can invoke it thus:
prompt adam2 [ 8bit ] [<color1> [<color2> [<color3>] [<color4>]]
where the colors are for the hyphens, current directory, user@host,
and user input bits respectively. The default colors are cyan, green,
cyan, and white. This theme works best with a dark background.
If you have the `nexus' or `vga' console fonts or similar, you
can specify the `8bit' option to use 8-bit replacements for the
7-bit characters.
And you probably thought adam1 was overkill ...
