+I've written over the years while doing Apple 2 hacking.

+make_b : take a machine language blob and give it the size/offset

+	 
+asoft_detoken: takes an applesoft file obtained with dos33
+               and converts it to an ASCII text file

+tokenize_asoft: takes an ASCII text file and converts it
+                into a tokenized applesoft file
