+This is at least a partial credits-file of people that have
+contributed to the Maple bootloader.  It is formatted the same way the
+Linux kernel CREDITS file is structured: sorted by name and formatted
+for easy processing.

+The fields are: name (N), email (E), web-address (W), description (D).

+
+stm32lib/*
+  - all the (possibly consolidated) stm32 lib and usb example code
+
+usb.c 
+  - USB-specific hardware setup. Interrupts, clocks, etc. handling USB when 
+    not "Attached". some low-level callbacks (low power mode, init, reset, 
+    resume, etc).
+
+usb_callbacks.c 
+  - aka endpoints: handling data transfer when "Configured". calls out to 
+    application specific callbacks (i.e. DFU).
+
+usb_descriptor.c 
+  - aka application descriptor; big static struct and callbacks for sending
+    the descriptor. 
+
+main.c
+  - main loop and calling any hardware init stuff. timing hacks for EEPROM 
+    writes not to block usb interrupts. logic to handle 2 second timeout then
+    jump to user code. 
+
+hardware.c
+  - init routines to setup clocks, interrupts, also destructor functions.
+    does not include USB stuff. EEPROM read/write functions.
+
+dfu.c
+  - mostly the giant FSM case switch, also some USB endpoint callbacks
+
+TODO --------------------------------------------------------------------------
+
+ * pack the structs
+ * use sizeof() for usb application descriptor once structs are packed
