    Yes, making fun of other people is the highest priority.

   Sorry I was not clear. ___I____  want to be able to continue with my simple-minded work flow and have it be compatible with what other people do. It is fine if Jed and Karl and Matt and whoever uses all kinds of cool Git features so long as it doesn't make ___my___ workflow too intellectually difficult for me. That is I only object to the change if it requires always wrestling with several new concepts that don't exist in Hg.  I do 

  hg clone
  hg pull
  hg commit
  hg merge
  hg push

I want to be able to do something similar with git; I don't want new __required__ things introduced like

  git sanitize  x y z 

where x y z are particular changing options that I HAVE to magically know what they are each time and get right or I fuck myself over.   Which did happen the one time I tried to use one of Jed's git repositories when it won't let me push because I hadn't indicated the right branch or some such shit. That is I don't want the repository system to require __me__ to keep in my brain any state information that I need to convey to the repository when interacting with it each time.

Sadly this is a very big argument for NOT switching PETSc to GIT. This email is only partly in jest, it has a serious component as well: is the "everyone's switching to git" just a case of the sheeple following the latest new thing without a proper technical evaluation or is it a carefully thought out decision?
