+# 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.
