This program is not really useful itself. It serves as testground of resolving symbols of shared objects from within the program code, without using libraries like libdl.

While the master-branch contains more or less clean code (how clean can code be, that calls internal functions of libc?), the make-it-small-branch is a rewrite with sickly focus on size. The code there may be used in a 4k intro, if it proves to be small enough.
