Very glad to receive your reply!
    In fact,write a svn client is not my real purpose,I only want to know
how the client communicate with the server.I have read the svnbook,and RFC
3253 that describe the webdav protocol.Then i use wireshark to get the
package to analysis.I checkout a directory from server,and find that in the
package there are two TCP flow,and many propfind request is the same.I
can't understand,so i think that if i know how to implement a client,i can
know why.Maybe i get the wrong way.
    in your reply you said "you should read "the book"
http://svnbook.red-bean.com/en/1.7/ and possibly the design documents in
the source tree, so you understand everything about subversion in general",
design documents include what?Is this "
http://svn.apache.org/repos/asf/subversion/trunk/notes/subversion-design.html".
I've read some of it,and now i'm still puzzled. In the checkout's
package,there are 16 propfind request in five types,can i use five propfind
request to finish the checkout operation?
    It's very glad to get your advise.Maybe my english is not tunnel,hope
you can catch my ideal.

> implementation which works without native code.
