如何设置SVN提交时强制添加注释

windows版本：
1、新建一个名为pre-commit.bat的文件并将该文件放在创建的库文件的hooks文件夹中
2、pre-commit.bat文件的内容如下：
@echo off
set SVN_BINDIR="C:\ProgramFiles\Subversion"
set SVNLOOK="E:\freescm\freescm\SVN\bin\svnlook.exe"
setlocal
set REPOS=%1
set TXN=%2
rem check that logmessage contains at least 10 characters
%SVN_BINDIR%\svnlook log “%REPOS%” -t “%TXN%” | findstr “……….” > nul
if %errorlevel% gtr 0 goto err
exit 0
:err
echo "提交文件时必须添加注释，提交中止." 1>&2
exit 1
