+# Variables (all optional, except GO_PKG) to be set in package
+# Makefiles:
+#
+# GO_PKG (required) - name of Go package
+#
+#   Go name of the package.
+#
+#   e.g. GO_PKG:=golang.org/x/text
+#
+#
+# GO_PKG_INSTALL_EXTRA - list of regular expressions, default empty
+#
+#   Additional files/directories to install. By default, only these
+#   files are installed:
+#
+#   * Files with one of these extensions:
+#     .go, .c, .cc, .cpp, .h, .hh, .hpp, .proto, .s
+#
+#   * Files in any 'testdata' directory
+#
+#   * go.mod and go.sum, in any directory
+#
+#   e.g. GO_PKG_INSTALL_EXTRA:=example.toml marshal_test.toml
+#
+#
+# GO_PKG_INSTALL_ALL - boolean (0 or 1), default false
+#
+#   If true, install all files regardless of extension or directory.
+#
+#   e.g. GO_PKG_INSTALL_ALL:=1
+#
+#
+# GO_PKG_SOURCE_ONLY - boolean (0 or 1), default false
+#
+#   If true, 'go install' will not be called. If the package does not
+#   (or should not) build any binaries, then specifying this option will
+#   save build time.
+#
+#   e.g. GO_PKG_SOURCE_ONLY:=1
+#
+#
+# GO_PKG_BUILD_PKG - list of build targets, default GO_PKG/...
+#
+#   Build targets for compiling this Go package, i.e. arguments passed
+#   to 'go install'.
+#
+#   e.g. GO_PKG_BUILD_PKG:=github.com/debian/ratt/cmd/...
+#
+#
+# GO_PKG_EXCLUDES - list of regular expressions, default empty
+#
+#   Patterns to exclude from the build targets expanded from
+#   GO_PKG_BUILD_PKG.
+#
+#   e.g. GO_PKG_EXCLUDES:=examples/
+#
+#
+# GO_PKG_GO_GENERATE - boolean (0 or 1), default false
+#
+#   If true, 'go generate' will be called on all build targets (as
+#   determined by GO_PKG_BUILD_PKG and GO_PKG_EXCLUDES). This is usually
+#   not necessary.
+#
+#   e.g. GO_PKG_GO_GENERATE:=1
+#
+#
+# GO_PKG_GCFLAGS - list of options, default empty
+#
+#   Additional go tool compile options to use when building targets.
+#
+#   e.g. GO_PKG_GCFLAGS:=-N -l
+#
+#
+# GO_PKG_LDFLAGS - list of options, default empty
+#
+#   Additional go tool link options to use when building targets.
+#
+#   Note that the OpenWrt build system has an option to strip binaries
+#   (enabled by default), so -s (Omit the symbol table and debug
+#   information) and -w (Omit the DWARF symbol table) flags are not
+#   necessary.
+#
+#   e.g. GO_PKG_LDFLAGS:=-r dir1:dir2 -u
+#
+#
+# GO_PKG_LDFLAGS_X - list of string variable definitions, default empty
+#
+#   Each definition will be passed as the parameter to the -X go tool
+#   link option, i.e. -ldflags "-X importpath.name=value".
+#
+#   e.g. GO_PKG_LDFLAGS_X:=main.Version=$(PKG_VERSION) main.BuildStamp=$(SOURCE_DATE_EPOCH)
+#
+#
+# GO_PKG_TAGS - list of build tags, default empty
+#
+#   Build tags to consider satisfied during the build, passed as the
+#   parameter to the -tags option for 'go install'.
+#
+#   e.g. GO_PKG_TAGS:=release,noupgrade
+#
+#
+# GO_PKG_INSTALL_BIN_PATH - target directory path, default /usr/bin
+#
+#   Directory path under "dest_dir" where binaries will be installed by
+#   '$(call GoPackage/Package/Install/Bin,dest_dir)'.
+#
+#   e.g. GO_PKG_INSTALL_BIN_PATH:=/sbin
+
+# Credit for this package build process (GoPackage/Build/Configure and
+# GoPackage/Build/Compile) belong to Debian's dh-golang completely.
+# https://salsa.debian.org/go-team/packages/dh-golang
