 *** Distinguishing features
     - /executable/ and /human readable/ knowledge (an /all time new/)
       + even hardware is... software! (VHDL, FPGA, ...)
       + /text files are forever/
     - naturally /evolves/ over time
       + the /development history/ is key to its /understanding/
     - complex: large /web of dependencies/, millions of SLOCs
 *** In a word
     - software /is not just another/ sequence of bits
     - a software archive /is not just another/ digital archive
