It's actually quite simple. LD_PRELOAD can achieve a similar effect, if the software is using the typical syscall library.

  I know exactly how it was done, I am just amazed that it was done. It's a great idea that I have never come up with, nor would I be able to.

    Yes, it's a great idea. A similar idea is used to trace what 'make install' does so that stuff can be uninstalled later - or made into a package (rpm, dpkg etc) I forget what that tool is called.

      Also similar in concept is the tup build system which monitors rule commands run to gain knowledge of additional dependencies. http://gittup.org/tup/ex_dependencies.html http://gittup.org/tup/ex_dependencies.html
