+# PLUGIN CACHING:
+#
+# Necessary to stop Terragrunt wasting tonnes of space
+#
+# You must create this cache dir manually otherwise Terraform will error out:
+#
+#    mkdir -p -v ~/.terraform.d/plugin-cache
+#
+# Otherwise Terraform / Terragrunt runs will error out like this...
+#
+#
+#   There are some problems with the CLI configuration:
+#   ╷
+#   │ Error: The specified plugin cache dir /Users/hari/.terraform.d/plugin-cache cannot be opened: stat /Users/hari/.terraform.d/plugin-cache: no such file or directory
+#   │
+#   ╵
+#
+#   As a result of the above problems, Terraform may not behave as intended.
+#
+#
+plugin_cache_dir   = "$HOME/.terraform.d/plugin-cache"
+#
+# Otherwise you could also waste space in these multiples... running this script from DevOps-Bash-tools repo:
