	Man oh Man 1.0 by Jim DeVona

	This script simply prompts the user for a term to look up in the
	system manual (man) pages. By default the results are displayed
	with Bwana, but the user can also opt to render the man pages as
	nice printable PostScript (converted to PDF) with Preview. The
	latter option takes longer.

	Bwana is a free utility available at http://www.bruji.com/bwana/ that
	renders man pages in your browser. It implements the "man:" URI scheme.

	The Preview method is based on this Mac OS X hint:

	Issues:
		Not much error checking, and its absence is particularly
		conspicuous around "do shell script", which could be confused
		by malformed input or a man query that yeilds no results.
