Stefan’s Tools is a small, but useful, set of tools created by Stefan Kueng, the main developer behind TortoiseSVN. Most notable is the StExBar utility, which is essentially everything Microsoft forgot to implement in Windows Explorer.
If you’re a fan of these tools, you can send a small donation his way for all the work he puts into these. Don’t use those tools, but love TortoiseSVN? You can support that instead (or both!).
For anyone who may be editing in TextPad, there’s a way you can have some Subversion functionality within the TextPad interface.
I don’t think I’ve ever used TextPad, but hopefully someone will find this useful.
I don’t know how I missed this before, but the TortoiseSVN and Tortoise Merge manuals are available on the TortoiseSVN website in both PDF and HTML formats. Unless you’re using a nightly build of TortoiseSVN, you’ll want to read the release version (not developer version). Older manuals are also available in case you’re not using v1.4.3.
