+**lua** library 
+
+Wait - this is a macro library - what is LUA doing here?  Well, it is a little known fact that you CAN run LUA within a SAS Macro.  It has to be written to a text file with a `.lua` extension, from where you can `%include` it.  So, without using the `proc lua` wrapper.
+
+To contribute, simply write your freeform LUA in the LUA folder.  Then run the `build.py`, which will convert your LUA into a data step with put statements, and create the macro wrapper with a `ml_` prefix.  You can then use your module in any program by running:
+
+```
+/* compile the lua module */
+%ml_yourmodule()
+
+/* Execute.  Do not use the restart keyword! */
+proc lua; 
+submit;
+  print(yourStuff);
+endsubmit;
+run;
+```
