+/**
+  @file mp_dictionary.sas
+  @brief Creates a portal (libref) into the SQL Dictionary Views
+  @details Provide a libref and the macro will create a series of views against
+  each view in the special PROC SQL dictionary libref.
+
+  This is useful if you would like to visualise (navigate) the views in a SAS
+  client such as Base SAS, Enterprise Guide, or Studio (or [Data Controller](
+  https://datacontroller.io)).
+
+  It works by extracting the dictionary.dictionaries view into
+  YOURLIB.dictionaries, then uses that to create a YOURLIB.{viewName} for every
+  other dictionary.view, eg:
+
+      proc sql;
+      create view YOURLIB.columns as select * from dictionary.columns;
+
+  Usage:
+
+      libname demo "/lib/directory";
+      %mp_dictionary(lib=demo)
+
+  Or, to just create them in WORK:
+
+      %mp_dictionary()
+
+  If you'd just like to browse the dictionary data model, you can also check
+  out [this article](https://rawsas.com/dictionary-of-dictionaries/).
+
+  @param lib= (WORK) The libref in which to create the views
