+MPW's `make` utility is similar to the Unix `make` utility.  Similar enough that some makefiles can be converted with simple text replacements.
+
+Here is an MPW makefile from IR 2.0.2 (ir.make):
+
+    IR ƒƒ IR.make ∂
+    		IRInit.aii.obj ∂
+    		RequestProc.aii.obj ∂
+    		IR.rfork
+    	LinkIIGS -t $B6 -at $0000 ∂
+    		IRInit.aii.obj ∂
+    		RequestProc.aii.obj ∂
+    		-o IR
+    		DuplicateIIgs -y -m IR :
+
+    IRInit.aii.obj ƒ IR.make IRInit.aii
+    	AsmIIGS -t IRInit.aii
+    RequestProc.aii.obj ƒ IR.make RequestProc.aii
+    	AsmIIGS -t RequestProc.aii
+    IR.rfork ƒ IR.make IR.r 
+    	RezIIgs IR.r -o IR.rfork
+    	Duplicate -r -y IR.rfork IR
+
+* `ƒƒ` and `ƒ` should be replaced with `:`.  
+* `∂` should be replaced with `\`.
+* `$` needs to be escaped as `\$$`.
+* mpw commands (AsmIIgs, LinkIIgs, RezIIgs, and Duplicate) are executed as _mpw command_ (unless you generate shell scripts for each command). 
+* the DuplicateIIgs command is no longer necessary.
+* if the makefile (IR.make) is included as a dependency, it should be updated to the new name.
+
+The modern makefile (makefile) is now:
+
+
+    IR : makefile \
+    		IRInit.aii.obj \
+    		RequestProc.aii.obj \
+    		IR.rfork
+    	mpw LinkIIGS -t \$$B6 -at \$$0000 \
+    		IRInit.aii.obj \
+    		RequestProc.aii.obj \
+    		-o IR
+        mpw Duplicate -r -y IR.rfork IR
+
+    IRInit.aii.obj : IR.make IRInit.aii
+    	mpw AsmIIGS -t IRInit.aii
+    RequestProc.aii.obj : IR.make RequestProc.aii
+    	mpw AsmIIGS -t RequestProc.aii
+    IR.rfork : IR.make IR.r 
+    	mpw RezIIgs IR.r -o IR.rfork
+
+(the Duplicate command was also moved from IR.rfork to IR since I prefer to set the resource fork after linking).
+
+More complicated makefiles involving variables require more work and editing.
