 STP is a constraint solver (also referred to as a decision procedure or
 automated prover) aimed at solving constraints generated by program analysis
 tools, theorem provers, automated bug finders, intelligent fuzzers and model
 checkers. STP has been used in many research projects at Stanford, Berkeley,
 MIT, CMU and other universities. It is also being used at many companies such
 as NVIDIA, some startup companies, and by certain government agencies.
 
 The input to STP are formulas over the theory of bit-vectors and arrays (This
 theory captures most expressions from languages like C/C++/Java and Verilog),
 and the output of STP is a single bit of information that indicates whether
 the formula is satisfiable or not. If the input is satisfiable, then it also
 generates a variable assignment to satisfy the input formula.
