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.
Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
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.
gc-utils is a small set of scripts that let you import and update CVS repositories into git very easy and let you export patches back into a CVS working copy. To makes the exchange easy, gc-utils stores the CVS working copy into a subdirectory and receives all information from there whenever necessary.
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.
