ViewVC (formerly known as ViewCVS) is a Python/CGI-based system for viewing and interacting with Subversion and CVS repositories through your Web browser. It can browse directories, view changelogs, generate diffs, view arbitrary revisions, and display annotated ("blame") listings. It has full support for tags and branches, and contains a database-backed query system like Bonsai. It was initially based on the cvsweb work by Henner Zeller, but has been ported to Python and dramatically enhanced.
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.
fs2svn takes a sequence of archive folders (snapshots or historical backups of a project) and makes a new Subversion repository, preserving their revision history. Each top-level folder creates one revision, which is backdated to its most recent file's modification date. Additions, changes, and deletions between one folder and the next are all recorded in the repository, and the efficient diff-based storage saves disk space over the original full or incremental backups.
SvnReporter generates various reports in response to commits happening in a Subversion repository. It is intended to be called from the post-commit hook. Two types of reports are supported: single-event and event list reports. The former generate reports relative to the current commit only, and are typically used to generate post-commit mails. The latter generate reports relative to a list of commits, e.g. an RSS feed or a Web page showing the latest commits. Reports can be restricted to certain criteria, specified by a list of regular expressions. The format of the reports can be defined with a template.
sccs2svn converts a SCCS repository into a Subversion repository. The script visits a directory tree with SCCS repositories. It then sorts the SCCS deltas by time and applies them to a Subversion repository. The script attempts to transform some SCCS keywords to Subversion keywords.
BelowVersion is a single-file Python CGI to browse a Subversion repository. It only needs a Web server with Python support and bindings for Subversion libraries. It bypasses the high-level client library for acceptable performance without losing features. It is written to be fast to navigate with mouse, both within a single revision and between revisions. It can provide revision logs, colored diffs, and a side-by-side view for image revisions. It can also serve the files like a normal (static) Web server, allowing plain view or saving to disk. It is written to be embeddable in other Web applications with little effort (explained in the source).
SVN2Log automatically generates changelogs from a Subversion repository. You do not need to waste your time and write a special changelog document with a subset of features already described in your SVN commits' descriptions; you decide which parts will be displayed for your users.
BundleMan manages the releases of an application built on versioned products under Subversion. An application is seen as a product suite defined using the Subversion svn:externals property. An application is a bundle of products. Products are versioned pieces of software. Releasing an application is about taking care of tagging the source repository, managing the version of each products, managing CHANGELOGs, creating a source package archive, and giving ways to maintain a release without blocking the trunk development.
