An Apache SVN client, right where you need it most
TortoiseSVN is a Subversion (SVN) client, implemented as a windows shell extension. Which means it's available right where you need it: in the Windows file explorer.
It's intuitive and easy to use, since it doesn't require the Subversion commandline client to run. Simply the coolest Interface to (Sub)Version Control!
Commandline utility to greatly simplify working with svn:ignore lists. Just use 'svnignore' to see all unversioned files, and 'svnignore -a' to ignore all unversioned files. Other options also exist.
