-Only two query operators are currently supported, "file" and "pattern".
+Three query operators are currently supported: "file", "pattern", and "name".
 
 The query "file=path/to/file.go" matches the package or packages enclosing
 the Go source file path/to/file.go.  For example "file=~/go/src/fmt/print.go"
-might returns the packages "fmt" and "fmt [fmt.test]".
+might return the packages "fmt" and "fmt [fmt.test]".
 
 The query "pattern=string" causes "string" to be passed directly to
 the underlying build tool. In most cases this is unnecessary,
 but an application can use Load("pattern=" + x) as an escaping mechanism
 to ensure that x is not interpreted as a query operator if it contains '='.
 
-A third query "name=identifier" will be added soon.
-It will match packages whose package declaration contains the specified identifier.
-For example, "name=rand" would match the packages "math/rand" and "crypto/rand",
-and "name=main" would match all executables.
+The query "name=identifier" matches packages whose package declaration contains

 All other query operators are reserved for future use and currently
 cause Load to report an error.
