+# @BLURB: basic eclass for building software written in the go
+# programming language that uses go modules.
+# @DESCRIPTION:
+# This eclass provides a convenience src_prepare() phase and some basic
+# settings needed for all software written in the go programming
+# language that uses go modules.
+#
+# You will know the software you are packaging uses modules because
+# it will have files named go.sum and go.mod in its top-level source
+# directory. If it does not have these files, use the golang-* eclasses.
+#
+# If the software you are packaging uses modules, the next question is
+# whether it has a directory named "vendor" at the top-level of the source
tree.
+#
+# If it doesn't, you need to create a tarball of what would be in the
+# vendor directory and mirror it locally. This is done with the
+# following commands if upstream is using a git repository:
+#
+# @CODE:
+#
+# $ cd /my/clone/of/upstream
+# $ git checkout <release>
+# $ go mod vendor
+# $ tar cvf project-version-vendor.tar.gz vendor
+#
+# @CODE:
+#
+# Other than this, all you need to do is inherit this eclass then
+# make sure the exported src_prepare function is run.
