 Another tool is pfunct, that can be used to find all sorts of information about
 functions, inlines, decisions made by the compiler about inlining, etc.
 
+One example of pfunct usage is in the fullcircle tool, a shell that drivers
+pfunct to generate compileable code out of a .o file and then build it using
+gcc, with the same compiler flags, and then use codiff to make sure the
+original .o file and the new one generated from debug info produces the same
+debug info.
+
+Pahole also can be used to use all this type information to pretty print raw data
+according to command line directions.
+
+Headers can have its data format described from debugging info and offsets from
+it can be used to further format a number of records.
+
+The btfdiff utility compares the output of pahole from BTF and DWARF to make
+sure they produce the same results.
