ubh - the Usenet Binary Harvester - is a GPL'ed Perl console application which automatically discovers, downloads, and decodes single-part and multi-part Usenet binaries. Automatically assembles multi-part binaries. Provides searching via Perl regular expression syntax. Also provides a pre-selection capability whereby the user can interactively choose which binaries to download. Uses a standard .newsrc file to control which groups and articles to process. Runs anywhere Perl runs. Tested under Unix-based Perl, Active Perl on Win32 platforms, and Mac OS X. Requires Net::NNTP and News::Newsrc (which itself requires Set::IntSpan), MIME::Parser, MIME::Base64, IO::Stringy, and MailTools (distribution).
