Details:

It might be helpful (especially for novice users) to clarify the error
message
avrdude: initialization failed, rc=-2
         Double check connections and try again, or use -F to override this
check.

In its current form, it doesn't really bring across that this will most likely
be a problem with the AVR not being powered, connected or clocked correctly.
People might blame their programmer instead, even though it is far less likely
to be broken than the AVR, its connections or clock source.

Also, when using a programmer that allows the user to set a custom SPI clock
frequency (e.g. the buspirate), the user should be reminded that the AVR's
clock frequency needs to be less than a quarter of the SPI frequency it is
programmed with. This might be appropriate to be mentioned in the manpage, and
putting it into the rc=-2 error message would be helpful, too.
