Most of that relates to the handling of the various Atmel tools, and 
best would be copied over from Atmel's device description file 
(ATmega16M1.atdf).  AVRDUDE simply passes these attributes over to 
the Atmel tools when talking to them.

The ATDF says erase delay is 45 ms for this part, the remaining values 
appear to be OK.

PAGEL and BS2 are the pin names of the respective parallel programming 
signals; PD7 and PE2 are OK here as well.
