PiSi is a modern package manager for UNIX systems. It has been designed to meet the requirements of the Pardus Linux distribution, and it is not derived from any other package manager. It is efficient and small. Package sources are written in XML and Python. Fast database access is implemented with Berkeley DB. It integrates both low-level and high-level package operations. Sources can be maintained easily through a version control system as original sources do not have to be copied. It uses a framework approach to build applications and tools upon. It has both a comprehensive CLI and a user-friendly Qt-based GUI.
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.
mkpkg is a small toolkit for automatically building Slackware or OpenLab packages. It should work on most packages that contain a makefile. It follows Slackware standards and is intended to build packages acceptable for linuxpackages.net. After you type the description, it generates a correctly formatted slack-desc file and logs configure options.
Slackselect is a package manager for Slackware that can install, remove, and upgrade packages. It can install/upgrade packages from FTP/HTTP and CD sets. It scans your installed packages, and can show you the packages that can be upgraded (and do it for you). It also finds obsolete packages that aren't in the distribution anymore. It was inspired by the functionality of dselect.
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.
FireAnt is an Eclipse plugin for modeling complex remote deployment and configuration processes for EJBs. It allows developers to model the deployment and execution of groups of packages and configuration scripts on remote targets. After modeling a deployment plan, FireAnt's runtime infrastructure SSHs into each target, copies over the specified files, deploys the EJBs and Webapps, runs any required deployment scripts, and then cleans the staging environment.
