-// Retime a single bit from one clock domain to another
-// Guarantees that no matter what the relative clock rates, if the in signal is high for at least
-//   one clock cycle in the clk_in domain, then the out signal will be high for at least one
-//   clock cycle in the clk_out domain.  If the in signal goes high again before the process is done
-//   the behavior is undefined.  No other guarantees.  Designed for passing reset into a new
-//   clock domain.
