可执行文件的改造技术

The Transforming Technique of the Executive File

引用成熟的可执行文件时我们常常感到需要扩展其功能，本论文给出了一种实现方法。作者把实现过程汇编成一个可执行文件，该文件主要功能是在用户输入的待扩展可执行文件的尾部添加扩展程序，并协调好控制权的移交。改造后的文件先执行扩展功能后执行原可执行文件的各项功能。

When quoting mature executive files, we constantly feel that it is necessary to extend their functions. The peper will introduce a method to realize it. In order to attain the goal, the author edits a program which mainly adds some extended programs to the original executive file and coordinates the relations between them. The new executive file will first execute the extended programs then the original parts while running.
