Here is the latest revision of these patches. I'll push them in a couple
days if there are no further comments.

+;; Commentary:
+;;
+;; Build procedures for Go packages.  This is the builder-side code.
+;;
+;; Software written in Go is either a 'package' (i.e. library) or 'command'
+;; (i.e. executable).  Both types can be built with either the `go build` or `go
+;; install` commands.  However, `go build` discards the result of the build
+;; process for Go libraries, so we use `go install`, which preserves the
+;; results. [0]
+
+;; Go software is developed and built within a particular filesystem hierarchy
+;; structure called a 'workspace' [1].  This workspace is found by Go
+;; via the GOPATH environment variable.  Typically, all Go source code
+;; and compiled objects are kept in a single workspace, but it is
+;; possible for GOPATH to contain a list of directories, and that is
+;; what we do in this go-build-system. [2]
+;;
+;; Go software, whether a package or a command, is uniquely named using
+;; an 'import path'.  The import path is based on the URL of the
+;; software's source.  Since most source code is provided over the
+;; internet, the import path is typically a combination of the remote
+;; URL and the source repository's filesystem structure. For example,
+;; the Go port of the common `du` command is hosted on github.com, at
+;; <https://github.com/calmh/du>.  Thus, the import path is
+;; <github.com/calmh/du>. [3]
+;;
+;; It may be possible to programatically guess a package's import path
+;; based on the source URL, but we don't try that in this revision of
+;; the go-build-system.
+;;
+;; Modules of modular Go libraries are named uniquely with their
+;; filesystem paths.  For example, the supplemental but "standardized"
+;; libraries developed by the Go upstream developers are available at
+;; <https://golang.org/x/{net,text,crypto, et cetera}>.  The Go IPv4
+;; library's import path is <golang.org/x/net/ipv4>.  The source of
+;; such modular libraries must be unpacked at the top-level of the
+;; filesystem structure of the library.  So the IPv4 library should be
+;; unpacked to <golang.org/x/net>.  This is handled in the
+;; go-build-system with the optional #:unpack-path key.
+;;
+;; In general, Go software is built using a standardized build mechanism
+;; that does not require any build scripts like Makefiles.  This means
+;; that all modules of modular libraries cannot be built with a single
+;; command.  Each module must be built individually.  This complicates
+;; certain cases, and these issues are currently resolved by creating a
+;; filesystem union of the required modules of such libraries.  I think
+;; this could be improved in future revisions of the go-build-system.
