神雕大侠写的Syslinux4USB是我在无忧论坛里找到的工具，他是2011年写出的，他在帖子里也发布了源码，可惜那个帖子里的链接失效了，我为了这个工具的源码找了2年，终于在Google上搜到了，并且修改了其中的代码，扩展了它的功能。
神雕的Syslinux4USB用的是syslinux 4.03的版本做的，syslinux 4.03版是2010年发布的，所以算是比较老的版本了，可能对新的硬件不太支持，所以我依次制作了Syslinux4USB 0.2和Syslinux4USB 0.3版本，分别采用syslinux 4.06和syslinux 6.02制作。增加了HDT（Hardware Detection Tool，硬件侦测工具）等一些功能，增加的功能都是从Grml Linux发行版的LiveCD中模仿来的。
从代码全局来看，主要分为版本模块、界面模块、语言模块、逻辑流程模块、U盘引导模块、文件部署模块等6个部分，我们仅仅需要改的是第一部分和最后一部分，也就是修改一下版本和要复制的文件就可以了。
首先，从定义的宏VERSION可以看出，这是用来定义版本的，如果你想修改程序名称和版本号，可以修改宏NAME和VERSION的内容。
然后下面就是修改复制的文件的部分，主要是修改File后的文件路径和名称，Copyfiles后面的文件路径和File后的文件路径对应，而后面的”$BootDir……”内容是用来指定syslinux所有文件放到U盘中的路径，必须逐个指定，File也需要逐个指定。
由于对NSIS的语法不了解，所以这篇文章只做分享，不做分析，有兴趣的可以翻译NSIS的手册。
最后，恐怕连神雕本人都想不到这个工具还会有后续版本，本文也算是对前辈的精神的回赠。
