While it won't be the most commonly used tool at the administrator's disposal, svndumpfilter provides a very particular brand of useful functionality—the ability to quickly and easily modify streams of Subversion repository history data by acting as a path-based filter.
The syntax of svndumpfilter is as follows:
$ svndumpfilter help general usage: svndumpfilter SUBCOMMAND [ARGS & OPTIONS ...] Type "svndumpfilter help <subcommand>" for help on a specific subcommand. Type 'svndumpfilter --version' to see the program version. Available subcommands: exclude include help (?, h)
There are only two interesting subcommands:
They allow you to make the choice between implicit or
explicit inclusion of paths in the stream. You can learn
more about these subcommands and
svndumpfilter's unique purpose in the section called “Filtering Repository History”.
