+ SYNOPSIS
+ super low drain bamage, K.I.S.S., storage-less, session-less,
+ plugin-less, dependency-less, zero admin, single-source-file secure
+ captcha system for ruby and/or rails.

- # all of this in inlined in the BEGIN block below...
+ DESCRIPTION
+ raptcha manages image generation via a streaming controller. the result
+ is that *no* disk storage is ever needed for captcha images. it also
+ manages authentication via openssl(aes-256) encoded hidden fields which
+ are relayed through the form submission process, obviating the need for
+ session/database interaction for captcha validation. the library is
+ useful outside of rails, even from the command line.
- libdir = __FILE__.gsub %r'\.rb$', '/'
- begin
- $:.unshift libdir
- require 'pervasives'
- require 'attributes'
- require 'crypt/blowfish'
- ensure
- $:.shift
- end
- #--}}}
-=end
+ what this means to you is that you can have a nice looking, and easy to
+ customize, safe captcha solution in about 1 minute that requires zero
+ maintenance moving forward.
