How to provide SVN username/password to easy_install?

I'm trying to install Python EGG with easy_install, providing a URL of Subversion repository, where sources are hosted:

$ easy_install svn://user:secret@svn.example.com/repo/trunk/my-egg
Authentication realm: <svn://svn.example.com:3690> repo
Password for 'm开发者_C百科e':

The problem is that the repository is password protected. How can I provide the desired username/password to easy_install?

ps. The only way I see so far is to run svn info --username... beforehand in order to cache credentials for a current user.. But it's just a workaround.
