+# Handle Go Modules support
+#
+# When using Go Modules, the current working directory MUST be at or below
+# the location of the 'go.mod' file when the go tool is used, and there is no
+# way to tell it to look elsewhere.  It will automatically look upwards for the
+# file, but not downwards.
+#
+# To support this use case, we provide the `GO_WORKDIR` variable, which defaults
+# to `GO_IMPORT` but allows for easy override.

+
+# The '-modcacherw' option ensures we have write access to the cached objects so
+# we avoid errors during clean task as well as when removing the TMPDIR.
