# adam1 prompt theme

prompt_adam1_help () {

cat <<'EOF'
|
|
This prompt is color-scheme-able. You can invoke it thus:
|
|
|
|
prompt adam1 [<color1> [<color2> [<color3>]]]
|
|
|
|
where the colors are for the user@host background, current working
|
|
directory, and current working directory if the prompt is split over
|
|
two lines respectively. The default colors are blue, cyan and green.
|
|
This theme works best with a dark background.
|
|
|
|
Recommended fonts for this theme: nexus or vga or similar. If you
|
|
don't have any of these, then specify the `plain' option to use 7-bit
|
|
replacements for the 8-bit characters.
|
|
|
|
And you probably thought adam1 was overkill.
