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.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
slkbuild is a script inspired by makepkg from Arch that greatly simplifies the package building process in Slackware and derivatives. It parses an easy-to-create SLKBUILD meta-file and from that creates a conventional build script that follows all of the Slackware packaging standards and that can be run on its own. The advantage of using slkbuild is that it ensures package uniformity and allows for an easy-to-edit meta-file in the event that one might require customization or might need to update the script for new releases. It also makes the build process much quicker, since it takes care of downloading the source, untarring, gzipping man and info pages, stripping binaries, making sure that the menu entry for a graphical application is compliant, as well as a host of other things.
BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by zlib. Functions are provided that transparently access files being either real files or zipped files, both with the same filepath. The zip-archive can be used in the place of a normal subdirectory. It is written in portable C.
pkg++ is a tool to build packages. The goal is to provide a tool you can use to build a package from a generic recipe on your distribution/OS and for your native package manager. The recipes, when done correctly, can be used on multiple OSes, and thus users can share them even if they do not use the same distribution. It is as much a way to easily package as it is a way to create multi-OS package recipes repositories.
ISO Master is an easy to use GUI CD image editor for Linux, BSD, and Windows. Basically, you can use this program to extract files from an ISO, add files to an ISO, and create bootable ISOs, all in a graphical user interface. It can open both ISO and NRG files, but can only save as ISO. It is based on bkisofs, a library for reading, modifying, and writing ISO images.
