-// This encoding, called UNSIGNED5, is taken from J2SE Pack200.
-// It assumes that most values have lots of leading zeroes.
-// Very small values, in the range [0..191], code in one byte.
-// Any 32-bit value (including negatives) can be coded, in
-// up to five bytes.  The grammar is:
-//    low_byte  = [0..191]
-//    high_byte = [192..255]
-//    any_byte  = low_byte | high_byte
-//    coding = low_byte
-//           | high_byte low_byte
-//           | high_byte high_byte low_byte
-//           | high_byte high_byte high_byte low_byte
-//           | high_byte high_byte high_byte high_byte any_byte
-// Each high_byte contributes six bits of payload.
-// The encoding is one-to-one (except for integer overflow)
-// and easy to parse and unparse.
