libgd-securityimage-perl binary package in Ubuntu Mantic amd64

 The (so called) "Security Images" are so popular. Most internet
 software use these in their registration screens to block robot programs
 (which may register tons of fake member accounts). Security images are
 basicaly, graphical CAPTCHAs (Completely Automated Public
 Turing Test to Tell Computers and Humans Apart). This
 module gives you a basic interface to create such an image. The final
 output is the actual graphic data, the mime type of the graphic and the
 created random string. The module also has some "styles" that are
 used to create the background (or foreground) of the image.
 .
 If you are an Authen::Captcha user, see GD::SecurityImage::AC
 for migration from Authen::Captcha to GD::SecurityImage.
 .
 GD::SecurityImage is just an image generator. Not a captcha handler.
 The validation of the generated graphic is left to your programming
 taste.
