This fork is just a quick and dirty solution (commit log should be self-explanatory)
to provide what golang/go#31761 aims to provide
when it is done (currently scheduled for Go 1.14; Feb 2020).

**NOTE**

APIs exposed from this module (esp. from modfile package) are
subject to change and everyone is encouraged to migrate
to `golang.org/x/mod` when it's feature complete and stable.

----

This repository holds packages for writing tools
that work directly with Go module mechanics.
That is, it is for direct manipulation of Go modules themselves.

It is NOT about supporting general development tools that
need to do things like load packages in module mode.
That use case, where modules are incidental rather than the focus,
should remain in x/tools, specifically x/tools/go/packages.

The specific case of loading packages should still be done by
invoking the go command, which remains the single point of
truth for package loading algorithms.
