The 64 Studio Platform Development Kit (PDK) is a version control system for GNU/Linux distributions, allowing the creation and management of many different projects, based on Debian and Ubuntu sources. PDK is written in Python, and the source code is well commented and contains documented examples.
The Ape Base Compile System is a set of scripts that leverage ESP EPM and MREPO to maintain Red Hat based systems that require custom and secluded binaries. It achieves cross platform reproducible compiles applications like Apache HTTPD, MySQL, and PHP, supports a common --prefix parent directory to allow different versions of an application to be installed, provides an easy method to switch between application versions, places selected application binaries in a central "bin" directory, supports delivery via Yum and other common installers, and provides a method for non-compiled "skeleton" files to be included with installation and distribution.
Cleverbox provides an interactive command line shell dedicated to the deployment and maintenance of Trac and Subversion instances. It can handle multiple configuration profiles, enabling the deployment of differently flavored types of projects (Trac configuration and permissions, Apache configuration templates, etc). The project's main objective is to make your life as simple as possible. Thus, it comes with easy installation, easy upgrades, and a comprehensive documentation.
svnauthcheck checks the syntax of a subversion authorization file and generates Apache-like permission specifications to be used by other tools such as ViewVC. svnauthcheck, in combination with subversion pre- and post-commit hooks, can be used to delegate the administration of a repository authorization to the end users.
ControlTier is a set of tools and an automation framework for deploying and managing multi-tier Web applications (or any application stack). It orchestrates the deployment and updating of code, data, and content across multiple physical, virtual, or cloud-based servers or clusters. Multiple tools include a command dispatching framework, a self-service Web interface, a multi-purpose CMBD/inventory tool, and a reporting infrastructure. Tools can be used individually or as an integrated system for large scale use.
The svnmailer is a tool that is usually called by a subversion hook to submit commit notifications in various ways (at the moment: mail via SMTP or a pipe to a sendmail like program, news via NNTP, or CIA live tracker notification via XML-RPC). It is derived from the original mailer.py distributed with subversion, but should be much more consistent, more extensible, and have many more features.
