-* A BigUnsignedInABase object represents a nonnegative
-* integer of size limited only by available memory,
-* represented in a user-specified base that can fit in
-* an `unsigned short' (most can, and this saves memory).
-*
-* BigUnsignedInABase is intended as an intermediary class
-* with little functionality of its own. BigUnsignedInABase
-* objects can be constructed from, and converted to,
-* BigUnsigneds (requiring multiplication, mods, etc.) and
-* `std::string's (by switching digit values for appropriate
-* characters).
-*
-* BigUnsignedInABase is similar to BigUnsigned. Note the following:
-*
-* (1) They represent the number in exactly the same way, except
-* that BigUnsignedInABase uses ``digits'' (or Digit) where BigUnsigned uses
-* ``blocks'' (or Blk).
-*
-* (2) Both use the management features of NumberlikeArray. (In fact,
-* my desire to add a BigUnsignedInABase class without duplicating a
-* lot of code led me to introduce NumberlikeArray.)
-*
-* (3) The only arithmetic operation supported by BigUnsignedInABase
-* is an equality test. Use BigUnsigned for arithmetic.
