+NVM / Node Package Manager
+==========================
+
+Makefiles beneath node-js/ maintain nvm and node package installs.
+
+Directories:
+
+- $(sandbox)/.tmp
+  - $(sandbox)/.tmp/.nvm
+  - $(sandbox)/.tmp/node_modules
+
+| Command | Description |
+| ------- | ----------- |
+| make npm-groovy-lint | Install the groovy linting tool  |
+| make sterile         | Remove .tmp/{.nvm, node_modules} |
+
+nvm/install.sh
+--------------
+
+Install script is downloaded from an external source so makefile targets
+at present are only intended for interactive use.  Install script could
+be checked in and trusted packages proxied but a review of copyrights,
+etc need to happen first.
+
+Node Packages in use:
+---------------------
+
+- npm-groovy-lint
