# description: HARVEST is an integrated set of tools to gather, extract,
#	       organize, and search information across the Internet.
#	       The GATHERER retrieves information resources using a variety
#	       of standard access methods (FTP, Gopher, HTTP, NNTP, and local
#	       files), and then summarizes those resources in various
#	       type-specific ways to generate structured indexing information.
