OK, here's the question I have with hooks. Is .tmpl designed to run on non-Windows PCs that are in the hooks folder and you need to create your own .bat files to run subversion hooks on Windows?
Yes, you can rename .tmpl to .bat. Hook scripts must be windows executable. You can also provide .exe files.
The script examples are pretty simple and shouldn't be too problematic.
Yup .. files .tmpl are samples. You will have to roll your own under windows. I would recommend using something like Perl or Python for batch files.
