 - OS independent
-- Not metadata aware
+- Works on all SAS Platforms
 - No X command
 - Prefixes: _mf_, _mp_

+- OS independent
+- Works on all SAS Platforms
+- No X command
+- Prefixes: _mddl_(lib)_ -> where lib can be "SAS" (in relation to a SAS component) or "DC" (in relation to a Data Controller component)
+
+This library will not be used for storing data entries (such as formats or datalines).  Where this becomes necessary in the future, a new repo will be created, in order to keep the NPM bundle size down (for the benefit of those looking to embed purely macros in their applications).

+#### FCMP library (All Platforms)
+
 - Function and macro names are identical, except for special cases
 - Prefixes: _mcf_
 
-The fcmp macros are used to generate fcmp functions, and can be used with or
-without the `proc fcmp` wrapper.

 * `insert_cmplib` option of mcf_xxx macros will be deprecated (the option is now checked automatically with value inserted only if needed)
 * mcf_xxx macros to have `wrap=` option defaulted to YES for convenience.  Set this option explicitly to avoid issues.
 * mp_getddl.sas to be renamed to mp_ds2ddl.sas (consistent with other ds2xxx macros).  A wrapper macro is already in place, and you are able to use this immediately.  The default for SHOWLOG will also be YES instead of NO.
