TL.EXE
__________________________________________________________________________
完全取代more、type、tail的强悍工具，采用64位流指针，支持数GB的超大文本，
瞬间读取任意位置。

智能识别文本编码，支持定义添加任意国编码识别框架，自动判断BOM类型。原生支持
ANSI、UTF8、Unicode、Unicode big endian、BIG5台湾编码。准确识别有无BOM类型、
可自定义行长、编码检测阈、跟随阈。

支持按行读取、按百分比读取。瞬移指针，无等待。 实时侦测文件末端最新行的改变，
最大可支持数TB巨型日志。时间仓促，仅在WIN7企业版32位下测试，其它系统请自行
测试、酌情试配。

使用：
	tl  [file] [-n&num1,num2]|[-p&per1,per2]|[-i]|[-d&num]
__________________________________________________________________________
选项：
	-h    显示帮助信息
	-n    读取第num1行到第num2行的内容
	-p    按百分比读取文件内容从per1到per2，注：取值为[0,1]内的小数
	-i    显示文本的行数、文件大小
	-d    侦测文件的最新num行，静态显示
	-d    无参数则采取强制跟随策略，即毫秒跟随，动态显示
	空    无开关则读取整个文件，支持7种编码
__________________________________________________________________________
示例：
         tl a.txt                      //显示a.txt文本内容；
         tl a.txt -i                   //显示a.txt行数及文件大小；
         tl a.txt -n3                  //从第3行读到结尾；
         tl a.txt -n3,5                //从第3行读到第5行；
         tl a.txt -p0.618,0.798        //显示文件的百分之几的内容
         tl a.txt -d15                 //侦测文件最新15行的变动，按Q键中断
         tl a.txt -d                   //强制跟随文件变动，毫秒级响应
