designed to be used by Unix distribution developers, package developers, and system implementors. Intended to be a reference, not a tutorial on how to manage a Unix filesystem or directory hierarchy.
This document explores methods for squeezing excess bytes out of simple programs. (Of course, the more practical purpose of this document is to describe a few of the inner workings of the ELF file format and the Linux operating system. But hopefully you can also learn something about how to make really teensy ELF executables in the process.)
