This prompt is color-scheme-able.  You can invoke it thus:

  prompt e101 [<text-color> [<parentheses-color>]]

The default colors are both blue. 

It shows:
user@host - tty - date - uname/dist
history_num - 3 dirs of path -

And has been tested on FreeBSD, Linux and OS X (for which it shows the version of OS X as well as Darwin)
