changetrack is a program to monitor changes to files. If files are modified one day, and the machine starts working incorrectly some days later, changetrack can provide information on which files were modified, and help locate the problem. Changetrack will also allow recovery of the files from any stage.
ded, the directory editor, allows you to navigate multiple file lists or a directory tree, viewing or changing file attributes rapidly. In addition to conventional file information, it operates on files' RCS or SCCS archives, making it useful for source control as well as system administration. It is curses-based.
Cvs-Brancher establishes a tagged branch in a CVS module and schedules a merge and build to occur at a later date/time. It might be used to roll out Website changes at odd hours, such as posting a press release in time for the start of the business day on the east coast, or to roll out cfengine changes to a data center during the night, to minimize the impact of downtime.
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.
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.
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.
