  * This program is designed so that it can be both:
- * (1) Run on the native machine and generated output
- * (2) Converted to assembly and parsed by genassym.awk
- *     to produce the same output as (1) does.
+ * (1) Run on the native machine to generate assym.h
+ * (2) Converted to assembly that genassym.awk will
+ *     translate into the same assym.h as (1) does.
  * The second method is done as follows:
  *   m68k-xxx-gcc [options] -S .../genassym.c
  *   awk -f genassym.awk < genassym.s > assym.h
+ *
+ * Using actual C code here (instead of genassym.cf)
+ * has the advantage that "make depend" automatically
+ * tracks dependencies of this C code on the (many)
+ * header files used here.  Also, the awk script used
+ * to convert the assembly output to assym.h is much
+ * smaller and simpler than sys/kern/genassym.sh.
+ *
+ * Both this method and the genassym.cf method have the
+ * disadvantage that they depend on gcc-specific features.
+ * This method depends on the format of assembly output for
+ * data, and the genassym.cf method depends on features of
+ * the gcc asm() statement (inline assembly).
