Aphid (the Apache/Perl HTTP Installation Daemon) provides a quick facility for compiling and installing the Apache Web server with support for SSL via mod_ssl, and with the embedded Perl interpreter provided by mod_perl. It downloads, compiles, and installs the software into the directory of your choice. Aphid places emphasis on providing an intuitive, browser-based interface and keeping a tiny distribution footprint. To date Aphid has been tested on Rehat Linux 6 and 6.2, FreeBSD 4.0, and Solaris 2.6 and 7.
Graft provides a mechanism for managing multiple packages under a single directory hierarchy. It was inspired by both Depot (from Carnegie Mellon University) and Stow (by Bob Glickstein). Packages are installed in self-contained directory trees and symbolic links from a common area are made to the package files.
DSWIM is a powerful informational tool for Debian's packaging system. Designed with an integrated approach it combines the functionality found in several other programs and scripts. This provides users with a centralized approach for querying the installation, allowing programmers the liberty of writing smaller and simpler code.
SystemImager automates the installation of Linux to masses of similar machines. Software distribution, configuration, and operating system updates are made easy, including updates from one Linux release to another. It can also be used for content distribution on Web servers. It is most useful in environments with large numbers of identical machines. Some typical environments include Internet server farms, high performance clusters, computer labs, and corporate desktop environments where all workstations have the same basic hardware configuration.
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.
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.
Debarchiver is a simple version of the official Debian archive tool katie. It sorts packages in a way similar to the potato archives. You can use it for publishing test versions or alternative packages, or simply to sort the programs you have created. It can also generate the Packages and Source files needed by apt.
Tepatche is a patch management system for OpenBSD. It will periodically check a specified FTP site, and if there is a new patch to be applied, downloads, applies, builds and installs it. Tepatche mantains a small status database to know in what is the status of each of the system's patches.
