makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.
Releaser is a set of scripts to automate and manage the tasks related to software package releases. It is designed to be modular and to make it easy to both select a particular set of actions associated with releases of a particular project (such as changelog generation, uploading of tarballs, posting announcements to mailing lists), and create new actions that integrate seamlessly into the process. Its status is still somewhat experimental, but the most basic functionality is there.
