+# 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, git-svn, hg, darcs, bzr, mtn, svn, cvs 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)
+# branchformat - Some backends replace %b in the prompt*format
+# styles above, not only by a branch name but also
+# by a revision number. This style let's you
+# modify how that string should look like.
+# enable - Check in the 'init' context. If set to false,
+# vcs_info() will do nothing.
+# disable - Provide a list of systems, you don't want
+# the prompt to check for repositories (checked
+# in the 'init' context, too).
+# use-simple - If there are two different ways of gathering
+# information, you can select the simpler one
+# by setting this style to true; the default
+# is to use the not-that-simple code, which is
+# potentially a lot slower but might be more
+# accurate in all possible cases.
+#
+# The use-simple style is currently only available for the bzr backend.
+#
+# The default values for these in all contexts are:
+# promptformat " (%s)-[%b|%a]-"
+# promptactionformat " (%s)-[%b]-"
+# branchformat "%b:%r" (for bzr, svn and svk)
+# enable true
+# disable (empty list)
+# use-simple false
+#
+# In the prompt*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'.
+#
+# In branchformat these replacements are done:
+# %b - the branch name
+# %r - the current revision number
+#
+# Not all vcs backends may support all replacements
+#
+# Examples:
+# Don't use vcs_info at all (even though it's in your prompt):
+# % zstyle ':vcs_info:*' enable false
+#
+# Don't provide prompt info for bzr and svk:
+# % zstyle ':vcs_info:*' disable bzr svk
+#
+# Provide a prompt specifically for git:
+# % zstyle ':vcs_info:git' promptformat ' GIT, BABY! [%b]'
+# % zstyle ':vcs_info:git' promptactionformat ' GIT ACTION! [%b|%a]'
+#
+# Use the quicker bzr backend (if you do, please report if it does
+# the-right-thing[tm] - thanks):
+# % zstyle ':vcs_info:bzr' use-simple true
+#
+# Display the revision number in yellow for bzr and svn:
+# % zstyle ':vcs_info:(svn|bzr)' branchformat '%b%{'${fg[yellow]}'%}:%r'
+#
+# If you want colors, make sure you enclose the color codes in %{...%},
+# because the string provided by vcs_info() is used for prompts.
+#
+# Example: PROMPT='%(?..[%?]-)%3~%$(vcs_info)#'
+#
+# This *requires* 'setopt prompt_subst'.
