 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
 #    2) Add the following line to your .bashrc/.zshrc:
 #        source ~/.git-completion.sh

-#    3) Consider changing your PS1 to also show the current branch:
-#         Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-#         ZSH:  PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
-#
-#       The argument to __git_ps1 will be displayed only if you
-#       are currently in a git repository.  The %s token will be
-#       the name of the current branch.
-#
-#       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
-#       value, unstaged (*) and staged (+) changes will be shown next
-#       to the branch name.  You can configure this per-repository
-#       with the bash.showDirtyState variable, which defaults to true
-#       once GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-#       You can also see if currently something is stashed, by setting
-#       GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-#       then a '$' will be shown next to the branch name.
-#
-#       If you would like to see if there're untracked files, then you can
-#       set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
-#       untracked files, then a '%' will be shown next to the branch name.
-#
-#       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
-#       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
