AgileSCM is an application lifecycle management solution for Subversion, Git, and Mercurial. It allows you to spend more time developing and less time fighting development tools or tied up with administration. AgileSCM is a user friendly, browser-based interface which abstracts developers from the complications of SVN, Mercurial, and Git.
TkCVS is a cross-platform, Tcl/Tk-based GUI for the CVS and Subversion configuration management systems. It displays the status of the files in the current working directory, and provides buttons and menus to execute CVS, Subversion, or RCS commands on the selected files. The Log Browser displays a branch diagram of the revision history. The Module Browser extends CVS with facilities for a user-friendly listing of modules in the repository. TkDiff is included for browsing and merging your changes.
SmartSVN is a feature-rich and easy-to-use Subversion client. It runs on Linux, Mac OS X, Unix, and Windows. In addition to the normal SVN commands like checkout, update, commit, merge, etc., it provides tag and branch handling (no need to deal with URLs just to switch to a different tag or branch), a built-in file compare and conflict solver, and much more. There is no need to install additional tools for handling SVN working copies, like a command line SVN client or a file comparison tool.
XML-Grammar-Fiction is a Perl package that provides processors for lightweight markup languages and corresponding XML grammars for writing prose (e.g. stories, novels, and novellas) as well as screenplays. The XML grammars can in turn be translated to XHTML and DocBook/XML. XML-Grammar-Fiction currently offers only very basic functionality, but has good support for UTF-8 and allows one to write bidirectional texts conveniently. It is still under development and may exhibit some quirks.
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.
Syncro SVN Client makes document and code sharing between content authors or developers easier. It offers full SVN repository support: checkout, export, import, copy, mkdir, rename, branch, tag, and delete. You can browse repositories, check for changes, commit changes, update your working copy, and examine the revision history. There is no need to install separate applications like a Subversion command line client or a file comparison tool.
