Ubh

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).
