Thanks, Ed.  I hadn't realized that was unidirectional, and that it was a 
user-implemented thing.  I think I saw something at SF about how to mirror a GH 
project, so I thought it went both ways.

So the recommended workflow is (from memory, I probably got some detail or 
option wrong):

git pull origin master                  #update local repository
git checkout -b problembranch   #create a local branch
#fix a problem
git add filename(s)                             #add files to staging area
git commit                                      #commit the changes to the 
local problembranch
git push origin problembranch           #push the branch to SF
#after a few minutes, log into GH, go to problembranch and initiate a pull 
request
#Wait for the automatic build tests to run and pass
#Wait for somebody to look at and approve the code if it is complicated
#DON'T merge and delete the branch on GH, ignore the tempting buttons
git rebase master                               #rebase the branch onto master
git checkout master                             #still rebasing
git merge problembranch —ff-only        #finally done rebasing
git push origin master                  #push to SF
git push origin :problembranch  #delete the remote branch
git branch -d problembranch             #delete the local branch

Part of me is yearning for those bygone CVS days, where we had one central 
repository and nobody knew how to branch so everything just got done on master 
and you couldn't do hardly anything without a network connection:

cvs update -d           #update local repository
#fix a problem
cvs commit              #push changes 

In other news, I got to show my son how to use a joystick on a working Apple 
IIe at the library yesterday.  Now if you'll excuse me, I have to get back to 
looking at these Polaroids through my rose-tinted glasses…

cheers,
Derek
