The Services_Google package is simply a wrapper around the SOAP extension and is used
to access the Google Web APIs (
http://www.google.com/apis/reference.html) for the search
engine, spelling suggestions, and cache. To access any of these services, you must obtain a
license key by registering for an account. A link to the registration page is available from the
previously mentioned URL. Because this package is a wrapper for SOAP, both PHP 5 and the
SOAP extension are prerequisites for installing and using this package.
