Thanks.  clone-depth seems not  to be available, so I amnot sure whats
best here.  I thinkI like the history, so I will see how to do a git
clone.  I do havethe type as git in the gentoo.conf, but I don't  know
what happened to clone-depth -- its not in the portage man page.

Thanks again -- this has beeninstructive for me.
