mkmed is a set of tools for maintaining software packages. The mkmed program automatically generates system- and configuration-independent intermediate files of a package, including build scripts. Unlike make, mkmed works bottom-up, so it can infer information you would otherwise have to express. mkmed-version creates a new distributable version of a package, and mkmed-tar creates a tarball of a distributable version.
Cinabox (Continuous Integration in a Box) automates the setup of a Continuous Integration (CI) system by doing The Simplest Thing That Could Possibly Work. It consists of two simple scripts to set up a cruisecontrolrb CI server from scratch on an Ubuntu 8.04 system: one script to bootstrap Ruby, and another script to set up CI.
Quilt is a set of scripts to manage a series of patches by keeping track of the changes each patch makes. Patches can be applied, un-applied, refreshed, etc. The key philosophical concept is that your primary output is patches, not ".c" files or ".h" files, so patches are the first-class object here. It was originally based on Andrew Morton's patch scripts published on the Linux kernel mailing list a while ago, but has been heavily modified since then.
The GNU Autoconf Archive is a collection of more than 450 macros for GNU Autoconf. They can be re-used without imposing any restrictions on the licensing of the generated configure script. In particular, it is possible to use them in configure scripts that are meant for non-free software.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
depfinder finds the dependencies of Slackware packages. The dependency list can be output to stdout, to a .dep text file without version information, or to a slack-required file with version information. depfinder is very fast; its speed is mainly due to the C++ code that is used in depfinder to find in which package each individual library is included. It also has support for running multiple jobs, which makes it a lot faster when used with multiple CPUs/cores. depfinder supports detecting dependencies of binary files compiled with languages such as C or C++ and it can also detect Python dependencies.
AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized. Output is specified with a Scheme-enhanced output template. Input, if required by your template, may come from AutoGen definitions, CGI data, or XML files.
