-// Amazon SimpleDB is a web service providing the core database functions of
-// data indexing and querying in the cloud. By offloading the time and effort
-// associated with building and operating a web-scale database, SimpleDB provides
-// developers the freedom to focus on application development.  A traditional,
-// clustered relational database requires a sizable upfront capital outlay,
-// is complex to design, and often requires extensive and repetitive database
-// administration. Amazon SimpleDB is dramatically simpler, requiring no schema,
-// automatically indexing your data and providing a simple API for storage and
-// access. This approach eliminates the administrative burden of data modeling,
-// index maintenance, and performance tuning. Developers gain access to this
-// functionality within Amazon's proven computing environment, are able to scale
-// instantly, and pay only for what they use.
+// SimpleDB provides the API operation methods for making requests to
+// Amazon SimpleDB. See this package's package overview docs
+// for details on the service.
