[Xastir] Format for .geo files

[drussell at gpgsecure.com]

Don't know if you guys know it or not, but Don Russell passed away last year, April 6th. He and I were very close friends. I don't know how many of you knew him or talked to him much but I thought I'd reply to this list since he was huge into HAM radio. All of his email comes to me now, but if you want to remove his email address from the list you may do so.

I don't know anything about HAM radio but I always remember him saying he had a lot of gear (and I've seen it) and that "People depend on this stuff so let Dad know if I'm ever gone."... so I don't know if when we unplugged it all everyone who was using it was like what the heck is going on, but... if one of you were wondering, there's your reason why...

Big loss... I still have a hard time getting over it. He and I spoke weekly for 25 years...
