Jeremi is groupware software for realtime document sharing. It supports distributed work on different documents or files by different people or project groups. It offers an always-up-to-date view of the project and its files and coordinates the dependency of the actual file status and access to those files. Jeremi is written entirely in Java.
Xfiles is an interactive utility for comparing and merging one file tree with another over a network. It supports freeform work on several machines (no need to keep track of what files are changed on which machine). Xfiles can also be used as a cross-validating disk<->disk backup strategy.
Subversion is a version control system. Originally designed to be a compelling replacement for CVS in the open source community, it has far exceeded that goal and seen widespread adoption in both open source and corporate environments. The Subversion project produces Subversion's core libraries (written in C), a fully functional command line client (svn), repository administration programs, API bindings for various languages (Perl, Python, Java, Ruby, etc.), and various additional tools and scripts.
Chora is built upon the Horde Application Framework and provides a read-only browser interface to any number of version control repositories. Advanced features include a visual branch view of the repository's history, pretty-printed output, annotation, patchsets and basic statistics.
XOTclIDE is an integrated (interactive) development environment for the Tcl and XOTcl language, a highly flexible object-oriented extension of Tcl. It provides a Smalltalk-like programming environment similar to Squick. It allows graphical introspection and editing of a running system (based on Tcl's and XOTcl's introspection facilities). The system state can be saved in the form of Tcl packages. It can optionally use a version control system based on a relational database (MySQL, PostgreSQL, ODBC, or SQLite). All system changes are saved to the database on the fly. It provides browsers for viewing and editing xotcl classes and objects. It also contains syntax highlighting and a static code checker for TCL and xotcl. It contains many developer plugins.
Cvsplot is a Perl script which analyzes the history of a CVS-managed project. The script executes on a set of files, analyzes their history, and automatically generates graphs that plot lines of code, number of files, and user contributions against time. It supports both UNIX and Windows environments.
Anthill is a tool that ensures a controlled build process and promotes the sharing of knowledge within an organization. Anthill performs a checkout from the source repository of the latest version of a project before every build and tags the repository with a unique build number after every build. It supports many reposistory adapters including: CVS (Concurrent Versions System), Visual Source Safe, Perforce, PVCS, StarTeam, MKSIntegrity, and FileSystem. Anthill also automatically updates a project intranet site with artifacts from the latest build. Anthill is an extension to the Apache-Ant project and is compatible with version 1.3, 1.4, and 1.5 of Ant.
