This module can be used to detect whether a visitor's user agent string indicates that it is a search engine spider. For example, if your site requires visitors to enter their age or country of residence before they enter, this can cause issues with search engine indexing. This module can be used to automatically allow search engine spiders to proceed into the site.
The user agent database comes from http://www.user-agents.org/
NOTE: Cloaking (changing content based on visitor or search engine spider) can cause penalties to be assessed to your search rankings. This module should not be used for this purpose.
Installation instruction are included in the package.
