OK.
... I'd keep the new ALIAS=evbearm* and remove the old ALIAS=evbarm*
lines, not provide both.
This ^^^ is actually why I have two aliase, because I personally
would keep the evbarm* style ones (since that's the port name) while
removing the evbearm* style ones, now that earm is the default.
I don't care which of the two you keep, but I think it's ugly to
have two aliases that mean the same thing.
If backward compatibility in alias names is important, then let's
at least invent a DEPRECATED keyword to mark the old aliases, or
use OALIAS= instead of ALIAS=. Adding a new keyword will not
require code changes, whereas adding OALIAS= will require a small
patch, such as the attached.

Would it be a problem for you if the alias names were changed? --apb (Alan Barrett) Not at all- I'll just regenerate my scripts. I was concerned that the aliases would be removed period because technically they're redundant. The aliases however, make generating my scripts easier.
