AutoRPM is a program that can do any combination of the following: mirror RPMs from an FTP site, keep installed RPMs consistent with an FTP site or local directory and keep installed RPMs in a cluster or network of systems consistent. It is highly flexible and contains a fully command-line driven interactive install mode (for installing RPMs from the queue or for installing RPMs from your system interactively). It also handles recursive dependencies, multiple versions of the same RPM, the same RPM with multiple architectures, and more. It does some of the same tasks as up2date and AutoUpdate.
rconftool is a reimplementation of Sam Varshavchik's sysconftool in Ruby. Its purpose is to keep configuration files "fresh" when upgrading an application from one version to another, ensuring that all necessary settings are present and that obsolete ones are removed. To use it, application writers need to distribute their config files marked up with some simple metadata in comments, and arrange for the "make install" or "make install-configure" target to invoke rconftool. rconftool can be called as a library function or from the command line. It can also install groups of files recursively from one directory tree into another.
Launch4j is a cross-platform tool for wrapping Java applications distributed as jars in Windows native executables. The executable can be configured to search for a certain JRE version or use a bundled one, and it's possible to set runtime options, like the initial/max heap size. The wrapper also provides better user experience through an application icon, a native pre-JRE splash screen, a custom process name, and a Java download page in case the appropriate JRE cannot be found. The increase in size of the application is small.
The Mknew Project is an investigation of how to build simple Unix shell scripts to manage common development and administrative tasks. The emphasis is on using languages and tools that already exist and are in common use. A related emphasis is on exploring the functional programming nature of the bash shell. This is accomplished by using the bash function capability, and using the bash "$(" ")"syntax to delay function execution in bash scripts. This allows building scripts that have a LISP-like function syntax that permits shell scripts to be written as a series of function calls with minimal syntax. The goal is to provide a way to specify make procedures of heterogeneous components in a bash script. These can include diverse source code languages, documentation text, test procedures, and data. In addition to the mknew function library (mklib), these "make" procedures rely only on capabilities provided by the bash shell, and common Unix command line utilities.
Devalot is a social networking application centered around software projects. It connects the user community with the development community and encourages participation and communication. It includes all the features you've come to expect in modern Web-based applications such as tagging, comments, and a wiki, as well as features you'd expect in project tracking software such as ticketing. It has features similar to some of those found in Trac, Collaboa, GForge, Mephisto, and Typo.
