How to merge svn project branches with local /usr/src?

[Nikolas Britton]

Hi,

I'm confused with the mechanics of merging a svn project branches into
/usr/src. I would like to merge the vps code, here:
http://svnweb.freebsd.org/base/projects/vps/ onto my FreeBSD 10-STABLE test
system. I presume svn merges everything into /usr/src automatically with
the right command(s)?

I feel like this is a dumb question, but I'm not familiar with the new svn
at all. The last time I used FreeBSD we did these things with cvs and diff
patches.

Thank you.
