Harvest is a system to collect information and make them searchable using a Web interface. It can collect information on Internet and Intranet using http, ftp, and nntp as well as local files like data on harddisk, CDROM, and file servers. Current list of supported formats in addition to HTML include TeX, DVI, PS, full text, mail, man pages, news, troff, WordPerfect, RTF, Microsoft Word/Excel, SGML, C sources, and many more. Stubs for PDF support are included and will use Xpdf or Acroread to process PDF files. Adding support for new format is easy due to its modular design.
