Configure username

 Hi,
I am trying to checkout my svn repo which is like

*svn+ssh://some/path/to/project/trunk*
And the user required for access to this repo is different than from my
ubuntu user, but it automatically picks the user from my ubuntu. How to
configure to use a different username than the system login user.

I tried
svn --username somename checkout svn+ssh://some/path/to/project/trunk

but it still not picks up the provided username.

signature?
