Alan Donovan 7d75e8b219 cmd/fiximports: a tool to rewrite import paths to match import comments.
fiximports enumerates the set of packages identified by the
command-line arguments, using "go list" notation.  Within each
package, it replaces all imports of non-canonical packages by their
canonical name, introducing an import renaming if (heuristically)
necessary.

If a package comes from one of the -baddomains, and it has no import
comment, fiximports reports an error.  The error message includes the
list of packages that import the errant package, directly or
indirectly.  This flag is used to indicate "sinking ship" package
hosting domains like code.google.com.

Caveat: this process is not trivially reversible.  Consider a package A
to which we add an import comment "B", and run the tool.  Package C,
which imported A, now imports B.  ('go get -u' would fetch package B).
But changing the import comment in directory A and re-running the tool
will not cause C to be changed because it no longer imports A; it
imports B.

+ Tests.

README

This subrepository holds the source for various packages and tools that support
the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.
Others, including the Go oracle and the test coverage tool, can be fetched with "go get".

Packages include a type-checker for Go and an implementation of the
Static Single Assignment form (SSA) representation for Go programs.
