Вот тебе русский сайт http://subversion.org.ru/
Только он, вроде как, не так давно начал функционировать, поэтому не очень посещается.
Там есть кое-какая переведенная документация.

А вот кусок из файла INSTALL.

E. Alternative: 'svnserve' and ra_svn
-----------------------------------

An alternative network layer is libsvn_ra_svn (on the client
side) and the 'svnserve' process on the server. This is a
simple network layer that speaks a custom protocol over plain
TCP (documented in libsvn_ra_svn/protocol):

$ svnserve -d # becomes a background daemon
$ svn checkout svn://localhost/usr/local/svn/repository

You can use the "-r" option to svnserve to set a logical root
for repositories, and the "-R" option to restrict connections to
read-only access. ("Read-only" is a logical term here; svnserve
still needs write access to the database in this mode, but will
not allow commits or revprop changes.)

'svnserve' has built-in CRAM-MD5 authentication (so you can
use non-system accounts), and can also be tunneled over SSH
(so you can use existing system accounts). Please read chapter
6 in the Subversion Book (http://svnbook.red-bean.com) for
details on these features.

P.S. Сам это не пробовал, но вроде несложно.

Вот кусок из svn-book.pdf :
SVNSERVE allows access to Subversion repositories standalone server process, or you can haveю Once the client has selected a repository svnserve.conf in the repository directory database to use and what authorization policies details of the svnserve.conf file.

Короче, всё равно придётся читать документацию.

Извиняюсь, предыдущий пост был споганен, не заметил. Ещё раз. Хотя тут идёт речь об Unix, но в Windows тоже есть svnserve.exe, и думаю что он работает без проблем.

svnserve allows access to Subversion repositories using the svn network protocol. You can run svnserve either as a standalone server process, or you can have another process, such as inetd, xinetd or sshd, launch it for you.
Once the client has selected a repository by transmitting its URL, svnserve reads a file named conf/
svnserve.conf in the repository directory to determine repository-specific settings such as what authentication
database to use and what authorization policies to apply. See the section called "svnserve, a custom server" for details
of the svnserve.conf file.
