== Specification ==

=== Constructor ===

`(make-bitvector ` [ ''size'' [ ''fill'' ] ]`)`

Returns a newly allocated bitvector.  If ''fill'' is omitted or `#f`, then all the bits are `#f`; if ''fill'' is `#t`, the the first ''size'' bits are `#t` and all other bits are `#f`.

=== Predicate ===

`(bitvector? `''obj''`)`

Returns `#t` if ''obj'' is a bitvector, and `#f` otherwise.

=== Bitwise operations ===

Same as BitwiseCowan, with appropriate name changes.

=== Mutators ===

Issue:  Linear update, or guaranteed mutation?

=== Conversion ===

`(bitvector->vector `''bv''`)`

`(vector->bitvector `''vec''`)`

`(bitvector->integer `''bv''`)`

`(integer->bitvector `''integer''`)`
