repos-tools is a set of command-line utilities to make work on your code repositories faster and easier. It lets you push, pull, build, and do other things on your repositories all at once. The supported (D)VCSes are Git, Subersion, Bazaar, and Mercurial. For GitHub users, forking, following, watching, and dealing with issues can be done from the shell.
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.
svncommit_hook.php was written to address the numerous problems with the commit_email.pl script which is bundled with subversion. Email messages sent by this script are sent as multipart messages with each diff in its own part. All of the parts are sent as nicely formatted HTML. It is possible to specify the charset of the files in the repository (the default is still UTF-8). Diffs are displayed only for the modified files. Diffs are colored. PHP files are validated with "php -l". It is possible to specify the URL of a corresponding Trac-resource, and the links to the files will be automatically included in the email.
Kumulate gives a graphical overview of progress on a tree of translation (.po) files. For each one, as well as showing the actual statistics, it will show a box: the horizontal (left-right) axis is a color-coded representation of progress on the translation, and the vertical (up-down) axis represents the relative size of the module or file.
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.
