I am able to check out an entire svn repository using the following command:
svn co https://myaccount.svn.beanstalkapp.com/myapp/
strange that your command works, i thougth it would need a target directory. but it looks like it assumes current pwd as default.
cd myapp
svn ci page1.html
you can also just do svn ci in or on that folder and it will detect all changes automatically and give you a list of what will be checked in
man svn tells you the rest
