+# Basic git handling - if you need more, check the plugin

+# This file provides several methods to inform your prompt about your
+# git status. All symbols and delimiters used can be customized.
+#
+# The variables and methods at a glance:
+#
+# git_prompt_info
+#   Shows your branch and whether your working tree is dirty or not.
+#   The string is delimited by
+#     ZSH_THEME_GIT_PROMPT_PREFIX
+#     ZSH_THEME_GIT_PROMPT_SUFFIX
+#   The symbols used to show dirtyness (evaluated in parse_git_dirty) are
+#     ZSH_THEME_GIT_PROMPT_DIRTY
+#     ZSH_THEME_GIT_PROMPT_CLEAN
+#   Can be disabled if GIT_HIDE == 'true' or through your git config (see
+#   check_git_show_status below)
+#   Dirty submodules are not tracked by this function if your git version
+#   if post 1.7.2
+#
+# git_prompt_short_sha and git_prompt_long_sha
+#   Delimited by
+#     ZSH_THEME_GIT_PROMPT_SHA_BEFORE
+#     ZSH_THEME_GIT_PROMPT_SHA_AFTER
+#
+# git_remote_status
+#   Shows the difference between your local and its remote branch. Checks
+#   for ahead, behind or diverged status and is shown with the help of
+#     ZSH_THEME_GIT_PROMPT_AHEAD
+#     ZSH_THEME_GIT_PROMPT_BEHIND
+#     ZSH_THEME_GIT_PROMPT_DIVERGED
+#
+# git_stash_status
+#   Shows whether you have stashed commits or not
+#     ZSH_THEME_GIT_PROMPT_STASHED
+#
+# git_prompt_status
+#   More detailed information about the status of your working tree. Shows
+#   what exactly makes it dirty and as a superset includes the information
+#   of git_remote_status and git_stash_status
+#     ZSH_THEME_GIT_PROMPT_ADDED
+#     ZSH_THEME_GIT_PROMPT_DELETED
+#     ZSH_THEME_GIT_PROMPT_MODIFIED
+#     ZSH_THEME_GIT_PROMPT_UNMERGED
