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.
svnauthcheck checks the syntax of a subversion authorization file and generates Apache-like permission specifications to be used by other tools such as ViewVC. svnauthcheck, in combination with subversion pre- and post-commit hooks, can be used to delegate the administration of a repository authorization to the end users.
