 `packelf` was inspired by [the idea of Klaus D](https://askubuntu.com/a/546305). It is used to pack a ELF program and its dependent libraries into a single executable file.

 First, pack a ELF program. For example, you can pack `ls` like this:

 However, every time the packed program is executed, an internal unpacking operation is performed automatically, which results in a slower startup of the program.
 
-If you need to execute the program many times and want to reduce the startup time, you can unpack the program before executing it.
