Nobody mention for Windows world SubWCRev, which, properly used, can substitute needed data into the needed places automagically, if script call SubWCRev in form SubWCRev WC_PATH TPL-FILE READY-FILE
Sample of my post-commit hook (part of)
SubWCRev.exe CustomLocations Builder.tpl z:\Builder.bat
...
call z:\Builder.bat
where my Builder.tpl is
svn.exe export trunk z:\trunk$WCDATE=%Y%m%d$-r$WCREV$
as result, I have every time bat-file with variable part - name of dir - which corresponds to the metadata of Working Copy
