Downloading sources from a SVN repository can already be done using
tools in base, but at the expense of a terrible inefficiency.

The FreeBSD SVN repositories are also accessible via http. The served
pages are _very_ easy to parse, as you can see from the
attachment. MD5 sums and all SVN properties are available through
WebDAV requests (not handled by the script).

I tried the attached script to download
http://svn.freebsd.org/base/stable/9/ In 27 minutes it downloaded 67
megabytes, corresponding to 42 KByte/sec, through an ADSL link capable
of roughly 400 KByte/sec. Then I stopped it.

IMHO this should demonstrate that the problem is not only having a
SVN workalike, but a fast and efficient one.
