　　;related plug-ins if needed
　　6.    .onMouseOverSection;鼠标放置的session发生变化是被调用，可以用于改变描述信息
　　;this callback is called whenever the mouse position over the sections tree has changed.this allows

　　;如果前面有'.un'前缀，则是卸载类型，名字中可以包含变量，which will be processed at runtime before the
　　components page shows.another way of changing the InstType name during runtime is the InstTypeSetText
　　command.the difference is that with InstTypeSetText you are saving your precious user variables,the first
　　type is the default (generally 'Typical').If the /NOCUSTOM switch is specified,then the "custom" install
　　type is disabled,and the user has to choose one of the pre-defined install types,Alternatively,if the

　　Compiler Flags
　　；编译选项
　　the following commands affect how the compiler generates code and compresses data.Unless otherwise noted,
　　these commands are valid anywhere in the script,and effect every line below where each one is placed until
　　overridden by another command,they cannot be jumped over using flow control instruction
　　46 AllowSkipFiles on|off
　　;on 时允许user skip file,off时，只有abort安装
　　this command specifies whether the user should be able to skip a file or not.
　　a user has an option to skip a file if SetOverwrite is set to on,and the installer fails to open a file
　　for writing when trying to extract a file. if off is used the ignore button which allows the user to skip
　　the file will not show and the user will only have an option to abort the installation
　　47 FileBufSize buffer_size_in_mb
　　;内存使用率
　　this command sets the size of the compiler's internal file buffers. This command allows you to control the
　　compiler's memory usage by limiting how much of a given file it will load into memory at once.since the
　　compiler needs both input and output,twice the memory size specified could be used at given time for file
　　buffers.
　　48 SetCompress auto|force|off
　　this command sets the compress flag which is used by the installer to determine whether or not data should
　　be compressed
　　49 SetCompressor [/SOLID][/FINAL] zlib|bzip2|lzma
　　;设置压缩算法，不能在section和functions中使用且必须在压缩前使用
　　this command sets the compression algorithm used to compress filese/data in the installer.
　　ZLIB: (the default) it is a quick and simple method, 300kb memory uses
　　BZIP2: gives better compression raios than ZLIB but a bit slower and uses more memory,4M memory uses
　　LZMA: a new compression method that gives very good compression ratios,compression speed is lower but 
　　decompression speed is high ,8M memory uses
　　if /FINAL is used,subsequent calls to SetCompressor will be ignored.即后面的调用将被忽略
　　if /SOLID is used,all of the installer data is compressed in one block,result in greater compression ratios
　　50 SetCompressorDictSize dict_size_mb
　　Sets the dictionary size in megabytes used by the LZMA compressor
　　51 SetDatablockOptimize on|off
　　;可以让压缩包更小，推荐on
　　this command tells the compiler whether or not to do datablock optimizations.Datablock optimizations have
　　the compiler check
　　52    SetDateSave on|off
　　this command sets the file date/time saving flag which is used by the File command to determine whether or
　　not to save the last write date and time of the file,so that it can be restored on installation.Valid flags
　　are 'on' and 'off' ,'on' is default
　　53 SetOverwrite on|off|try|ifnewer|ifdiff|lastused
　　;是否覆盖已经存在的文件
　　on 直接覆盖(default)
　　off 不覆盖
　　try 如果能覆盖则覆盖
　　ifnewer 如果存在的文件更旧
　　ifdiff 不同，更新或更旧
　　lastused
　　Version Information
　　54 VIAddVersionKey [/LANG=lang_id] keyname_value
　　add a field in the Version Tab of the File Properties,this can either be a field provided b the system
　　or a user defined field.The following fields are provided by the System:
　　.ProductName
　　.Comments
　　.CompanyName
　　.LegalCopyright
　　.FileDEescription
　　.InternalName
　　.LegalTrademarks
　　.OriginalFilename
　　.PrivateBuild

　　VIAddVersionKey /LANG=${LANG_ENGLISH} "LegalTrademarks" "Test Application is a trademark of Fake company"
　　VIAddVersionKey /LANG=${LANG_ENGLISH} "LegalCopyright" "? Fake company"
　　VIAddVersionKey /LANG=${LANG_ENGLISH} "FileDescription" "Test Application"
　　VIAddVersionKey /LANG=${LANG_ENGLISH} "FileVersion" "1.2.3"
　　55 VIProductVersion [version-string_X.X.X.X]
　　adds the Product Version on top of the Version Tab in the Properties of the file.
　　VIProductVersion "1.2.3.4"
　　Instructions
　　Basic Instructions
　　1. Delete [/REBOOTOK] file
　　删除文件(可以包含通配符也可以是绝对路径)
　　/REBOOTOK 选项指定重启后删除
　　找到文件但无法删除 error flag is set
　　没有找到文件error flag is not set
　　Delete $INSTDIR|test.dat
　　2. Exec command
　　执行指定的program,指定的程序必须存在 $OUTDIR is used for the working directory
　　指定程序无法启动时，error flag is set
　　Exec '"$INSTDIR\text.exe"'
　　Exec '"$INSTDIR\text.exe" some parameters'
　　3. ExecShell action command [parameters [SW_SHOWDEFAULT|SW_SHOWNORMAL|SW_SHOWMAXIMIZED|SW_ SHOWMINIMIZED|SW_HIDE]]
　　使用ShellExecute来执行一个程序，通常执行"open","print" 等
　　$OUTDIR 是工作目录
　　error flag is set 如果无法启动
　　ExecShell "open" "http://nsis.sf.net"
　　ExecShell "open" "$INSTDIR\readme.txt"
　　4. ExecWait command[user_var(exit code)]
　　执行一个程序且等待该程序进程结束，
　　if no ouput variable is specified
　　如果该程序没有返回值返回nonzero error code或执行出错，error flag is set,
　　if an ouput variable is specified
　　该函数将用exit code 填充变量,
　　ExecWait '"$INSTDIR\test.exe"'
　　ExecWait '"$INSTDIR\text.exe"' $0
　　ExecWait '"$INSTDIR\text.exe" some parameters'
　　5 File 
　　.output file name is $OUTDIR\filename_portion_of_file
　　.use /oname = x switch to 改变output name.x可以包含变量，可以是相对或绝对路径，若包含space 请加上""
　　.支持通配符
　　.if /r is used, 递归查找子文件夹
　　. /x is used to exclude files or directories.排除不需要的文件或文件夹
　　. /a is used,the attributes of the files added will be preserved. 
　　. if /nonfatal is used and no files are found,a warning will be issued instead of an error
　　File something.exe
　　File /a someting.exe
　　File *.exe
　　File /r *.dat
　　File /r data
　　File /oname=temp.dat somefile.ext
　　File /oname=$TEMP\temp.dat somefile.ext
　　File "/oname=$TEMP\name with spaces.dat" somefile.ext
　　File /nonfatal "a file that might not exist"
　　File /r /x CVS myProject\*.*
　　File /r /x *.res /x *.obj /x *.pch source\*.*
　　注意 /r
　　when using the /r switch,both mathing directories and files will be searched.this is always done with or without the use
　　of wildcards,even if the given path perfectly matches one directory,
　　6 Rename [/REBOOTOK] source_file dest_file
　　Rename source_file to des_file
　　if the current folder is not set using SetOutPath instruction the current folder is $EXEDIR
　　可以用来移动文件和目录
　　Rename $INSTDIR\file.ext $INSTDIR\file.dat
　　7 ReserveFile [/nonfatal] [/r] [/x file|wildcard [...]] file [file....]
　　Reserves a file in the data block for later use,
　　文件是按他们在脚本中出现的顺序添加到data block中，而函数则不是按他们出现的顺序被调用的
　　如果你在一个函数中添加一个文件，他会被早早的调用而你却把它定义在脚本的很后面，执行脚本时，all of the files added earlier will
　　have to be decompressed to get to the required file,
　　此函数可以节省装载时间，另外，先会被调用的函数定义到前面
　　8 RMDir [/r] [/REBOOTOK] directory_name
　　移除文件夹，绝对路径，
　　没有 /r时，只有文件夹为空时才会被移除，
　　有/r 时，文件夹被递归移除
　　/REBOOTOK 重启后移除
　　有error flag
　　RMDir $INSTDIR
　　注意：当前文件夹不能被移除， the current working directory is set by SetOutPath
　　SetOutPath $TEMP\dir
　　RMDir $TEMP\dir
　　The next example will succeed in deleting the directory.
　　SetOutPath $TEMP\dir
　　SetOutPath $TEMP
　　RMDir $TEMP\dir
　　使用RMDir/r $INSTDIR in the uninstaller is not safe though it is unlikely
　　因为如果用户指定 $INSTDIR 是 Program Files时，可能导致整个文件夹被删除
