This kind of thing is common in Linux, in fact, a lot of Linux 
software consists of a runner script that sets LD_LIBRARY_PATH 
and a separate binary file and its library .so files that is the 
actual application.

LD_LIBRARY_PATH tells it where to find the shared library files. 
Without it, the system only searches the global directories like 
/usr/lib.
