 This is a simple rubygem wrapper for the class written by Peter Cooper and posted to dzone.
 
 ## History
-v5 (added support for flags being on by default, instead of off)
-#              v4 (fixed bug where setting 0 bits to 0 caused a set to 1)
-#              v3 (supports dynamic bitwidths for array elements.. now doing 32 bit widths default)
-#              v2 (now uses 1 << y, rather than 2 ** y .. it's 21.8 times faster!)
-#              v1 (first release)

+## Description
 Basic, pure Ruby bit array. Pretty fast (for what it is) and memory efficient.
 Works well for Bloom filters (the reason I wrote it).
 
 Create a bit array 1000 bits wide
-```ruby  ba = BitArray.new(1000)```
+```ruby
+ ba = BitArray.new(1000)
+```
 
 Setting and reading bits
 ```ruby
-  ba[100] = 1
-  ba[100]    .. => 1
-  ba[100] = 0
+ba[100] = 1
+ba[100]    .. => 1
+ba[100] = 0
 ```
 
 More
 ```ruby
-  ba = BitArray.new(20)
-  [1,3,5,9,11,13,15].each { |i| ba[i] = 1 }
-  ba.to_s
-  #=> "01010100010101010000"
-  ba.total_set
-  #=> 7
+ba = BitArray.new(20)
+[1,3,5,9,11,13,15].each { |i| ba[i] = 1 }
+ba.to_s
+#=> "01010100010101010000"
+ba.total_set
+#=> 7
