+ * igen.c (main): Change -I option to -I<directory>. Add optional
+ size to -Ggen-icache option. Add -Gno-... support.
+
+ * igen.h (struct _igen_options): Add include field.

+ (table_open): Use table_push.
+ (table_read): Point variable file at current table, at eof, pop
+ last open table.
+
+ * table.h, table.c (table_push): New function.
