A package statement is said to have an “import comment” if it is immediately followed (before the next newline) by a comment of one of these two forms:
// import "path" / import "path" /
The go command will refuse to install a package with an import comment under any import path except the one named in the comment.
Continuing the example, as long as one file from package pdf contains
package pdf // import "rsc.io/pdf"
the go command will reject "go get github.com/rsc/pdf", ensuring that the code can be moved without breaking users.
