+## If you would like to see the difference between HEAD and its
+## upstream, set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates
+## you are behind, ">" indicates you are ahead, and "<>"
+## indicates you have diverged.  You can further control
+## behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated
+## list of values:
+##     verbose       show number of commits ahead/behind (+/-) upstream
+##     legacy        don't use the '--count' option available in recent
+##                   versions of git-rev-list
+##     git           always compare HEAD to @{upstream}
+##     svn           always compare HEAD to your SVN upstream
+##     auto          just the '<', '>', or '<>'
+## By default, __git_ps1 will compare HEAD to your SVN upstream
+## if it can find one, or @{upstream} otherwise.  Once you have
+## set GIT_PS1_SHOWUPSTREAM, you can override it on a
+## per-repository basis by setting the bash.showUpstream config
+## variable.
