I did a little googling and found that there isn\'t really a resource of SVN hooks for Windows. So I figured I\'d start a wiki here to centralize it.
If you contribute,
(branch-16E in this case):
setlocal
rem Subversion sends through the path to the repository and transaction id
set REPOS=%1
set TXN=%2
rem Committing to a branch is not allowed
svnlook changed -t %TXN% %REPOS% | findstr "\/branch-16E"
if %errorlevel% EQU 0 goto errb else exit 0
:errb
echo. 1>&2
echo This branch was closed. If you want to commit here contact your administrator. 1>&2
exit 1
