+# vcs_info() documentation: {{{
+#
+# The vcs_info () feature can be configured via zstyle:
+#   First, the context in which we are working:
+#       :vcs_info:<vcs-string>
+#   ...where <vcs-string> is one of: git, hg, bzr, svn or svk
+#
+#   You can of course use ':vcs_info:*' to match all VCSs at once.
+#
+# There is one special context named 'init', that is in effect as long
+# as there was no decision what vcs backend to use.
+#
+# There are currently two styles, that are looked up:
+#   promptformat        - Used in most circumstances.
+#   promptactionformat  - Used if a there is a special action going on;
+#                         (like an interactive rebase or a merge conflict)
+#   enable              - check in the 'init' context. If set to false,
+#                         vcs_info() will do nothing.
+#
+# The default values for these in all contexts are:
+#   promptformat        " (%s)-[%b|%a]-"
+#   promptactionformat  " (%s)-[%b]-"
+#   enable              true
+#
+# In these formats, the following replacements are done:
+#   %s  - The vcs in use (git, hg, svn etc.)
+#   %b  - Information about the current branch.
+#   %a  - An identifier, that describes the action.
+#         Only makes sense in promptactionformat.
+#   %R  - base directory of the repository.
+#   %r  - repository name
+#         If %R is '/foo/bar/repoXY', %r is 'repoXY'.
+#
+# Not all vcs backends may support all replacements
+#
+# If you want colors, make sure you enclose the color codes in %{...%}, because
+# the string provided by vcs_info() is commonly used for prompts.
+#
+#   Example: PROMPT='%(?..[%?]-)%3~%$(vcs_info)#'
+#
+# This *requires* 'setopt prompt_subst'.
