-// Package gcexportdata provides functions for locating, reading, and
-// writing export data files containing type information produced by the
-// gc compiler. This package supports go1.7 export data format and all
-// later versions.
-//
-// Although it might seem convenient for this package to live alongside
-// go/types in the standard library, this would cause version skew
-// problems for developer tools that use it, since they must be able to
-// consume the outputs of the gc compiler both before and after a Go
-// update such as from Go 1.7 to Go 1.8. Because this package lives in
-// golang.org/x/tools, sites can update their version of this repo some
-// time before the Go 1.8 release and rebuild and redeploy their
-// developer tools, which will then be able to consume both Go 1.7 and
-// Go 1.8 export data files, so they will work before and after the
-// Go update. (See discussion at https://golang.org/issue/15651.)
