Garrett has it spot on: in Perforce, the server has knowledge of the
clients, including the 'p4 edit'ed files and the open change lists,
while Subversion's server has no concept of its clients.

In my previous reply to this subject, I mentioned using TSVN as a
client, allowing you to select which files go into a checkin. If you
like using the command like, you could do something like what Garrett
mentions: using the 'commit --targets FILE' construct. The problem that
I've come across with this is remembering which files to check in. Have
a look at this post to easily find all the files you might checkin, and
then be able to select which files to check in through the command line:

Hope this helps.
