Command line use
TortoiseSVN includes an option to install SVN for the command line (be sure to tick the relevant option when installing). Once installed, you can use call svn from the command line just like on other operating systems. This can be useful when dealing with connection errors.
You can also call tortoiseproc to trigger GUI popups from the command line (see http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-automation.html for command details).
