apt-cacher is a CGI script which can be used by apt-get to request downloads of Debian packages (and release files) from the Net. Each downloaded file is cached into a directory, so subsequent requests for the same filename are filled from the cache. This is useful when you have multiple Debian installations to update, particularly if you are on the end of a slow Internet connection. apt-cacher is easy to install; you only need to have a local Web server on which you can place the CGI script and create a directory for the cache.
The poldek is an RPM package management tool which allows you to easily perform package verification, installation (including system installation from scratch), upgrading, and removal. Package dependencies are automatically handled, so if you try to install a package that needs others to be installed, it will download all needed packages and install them. It can be used in batch (like apt-get from Debian's APT) or interactive mode. The interactive mode puts you into a readline interface with commandline autocompletion and history, similar to the shell mode of Perl's CPAN.
cvsroot is a script to help keep track of multiple sites when using CVS, and in particular the CVSROOT and CVS_RSH environment variables for those sites. It creates a $HOME/.cvsroot file, with shortcut names representing the different CVS sites. The new environment variables appropriate to the site selected will then be set, and a new shell will be spawned to keep the variables. In this way, you do not have to keep setting the environment yourself, and can rely on the script to keep track of things for you.
RPMSV manages RPM packages installed on a system to determine which ones should be installed, deleted, or updated. This can be done with a single command. It has definitions of function groups to determine all packages needed for a specific function (such as serving web pages), and can do central maintenance of packages, versions, and function groups over many hosts.
Multicast BOOTP Java server and C/Linux client's goal is to implement the BOOTP/DHCP protocol through multicast rather than broadcast. Sun's Java networking API offers multicast socket communication objects, allowing you to create a platform independent IP interface configuration utility. Eventually, such utilities may become a fully featured multicast DHCP server. Any ideas on how to support existing BOOTP broadcast client requests are welcome. See the Multicast HOWTO at http://www.linuxdoc.org/HOWTO/Multicast- HOWTO.html.
