 WIP set of instructions for doing this. working to refine this down:
 
 - Add function/definitions to runtime.h and runtime.c
-- Add to prim? section in transforms.scm. Some functions may need to added to the next section in the file, so they are not constant-folded (IE, evaluated at compile time).
-- Add to the c-compile-primitive section in cgen.scm.
-- install modified .scm files
+- Rebuild and install runtime library.

+- Add to prim? section in transforms.sld. Some functions may need to added to the next section in the file, so they are not constant-folded (IE, evaluated at compile time).
+- Add to the c-compile-primitive section in cgen.sld.
+- install modified .sld files
 - cyclone scheme/cyclone/cgen.sld
 - copy modified files to cyclone-bootstrap, including cgen.c
 - install cyclone-bootstrap
 - run 'make clean ; make && make bootstrap' from cyclone repo
 - run 'make clean ; ./install' from bootstrap repo
 
+- Add primitives to the list in eval.sld
