+// The godex command prints (dumps) exported information of packages
+// or selected package objects.
+//
+// In contrast to godoc, godex extracts this information from compiled
+// object files. Hence the exported data is truly what a compiler will
+// see, at the cost of missing commentary.
+//
+// Usage: godex [flags] {path[.name]}
+//
+// Each argument must be a (possibly partial) package path, optionally
+// followed by a dot and the name of a package object:
+//
+// godex math
+// godex math.Sin
+// godex math.Sin fmt.Printf
+// godex go/types
+//
+// godex automatically tries all possible package path prefixes if only a
+// partial package path is given. For instance, for the path "go/types",
+// godex prepends "golang.org/x/tools".
+//
+// The prefixes are computed by searching the directories specified by
+// the GOROOT and GOPATH environment variables (and by excluding the
+// build OS- and architecture-specific directory names from the path).
+// The search order is depth-first and alphabetic; for a partial path
+// "foo", a package "a/foo" is found before "b/foo".
+//
+// Absolute and relative paths may be provided, which disable automatic
+// prefix generation:
+//
+// godex $GOROOT/pkg/darwin_amd64/sort
+// godex ./sort
+//
+// All but the last path element may contain dots; a dot in the last path
+// element separates the package path from the package object name. If the
+// last path element contains a dot, terminate the argument with another
+// dot (indicating an empty object name). For instance, the path for a
+// package foo.bar would be specified as in:
+//
+// godex foo.bar.
+//
+// The flags are:
+//
+// -s=""
+// only consider packages from src, where src is one of the supported compilers
+// -v=false
+// verbose mode
+//
+// The following sources (-s arguments) are supported:
+//
+// gc
+// gc-generated object files
+// gccgo
+// gccgo-generated object files
+// gccgo-new
+// gccgo-generated object files using a condensed format (experimental)
+// source
+// (uncompiled) source code (not yet implemented)
+//
+// If no -s argument is provided, godex will try to find a matching source.
+//
+package main // import "golang.org/x/tools/cmd/godex"
+
+// BUG(gri): support for -s=source is not yet implemented
+// BUG(gri): gccgo-importing appears to have occasional problems stalling godex; try -s=gc as work-around
