-    # When that's done and you enter a directory that matches the pattern
-    # in the third part of the context, a function called chpwd_profile_grml,
-    # for example, is called (if it exists).
-    #
-    # If no pattern matches (read: no profile is detected) the profile is
-    # set to 'default', which means chpwd_profile_default is attempted to

-    # A word about the context (the ':chpwd:profiles:*' stuff in the zstyle
-    # command) which is used: The third part in the context is matched against
-    # ${PWD}. That's why using a pattern such as /foo/bar(|/|/*) makes sense.
-    # Because that way the profile is detected for all these values of ${PWD}:
-    #   /foo/bar
-    #   /foo/bar/
-    #   /foo/bar/baz
-    # So, if you want to make double damn sure a profile works in /foo/bar
-    # and everywhere deeper in that tree, just use (|/|/*) and be happy.
-    #
-    # The name of the detected profile will be available in a variable called
-    # 'profile' in your functions. You don't need to do anything, it'll just
-    # be there.
-    #
-    # Then there is the parameter $CHPWD_PROFILE is set to the profile, that
-    # was is currently active. That way you can avoid running code for a
-    # profile that is already active, by running code such as the following
-    # at the start of your function:
-    #
-    # function chpwd_profile_grml() {
-    #     [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
-    #   ...
-    # }
-    #
-    # The initial value for $CHPWD_PROFILE is 'default'.
-    #
-    # Version requirement:
-    #   This feature requires zsh 4.3.3 or newer.
-    #   If you use this feature and need to know whether it is active in your
-    #   current shell, there are several ways to do that. Here are two simple
-    #   ways:
-    #
-    #   a) If knowing if the profiles feature is active when zsh starts is
-    #      good enough for you, you can put the following snippet into your
-    #      .zshrc.local:
-    #
-    #   (( ${+functions[chpwd_profiles]} )) && print "directory profiles active"
-    #
-    #   b) If that is not good enough, and you would prefer to be notified
-    #      whenever a profile changes, you can solve that by making sure you

+# This actually defines three prompts:
+#

+#    - grml-chroot
+#
+# They all share the same code and only differ with respect to which items they
+# contain. The main source of documentation is the `prompt_grml_help' function
+# below, which gets called when the user does this: prompt -h grml
+
+function prompt_grml_help () {
+    cat <<__EOF0__
+  prompt grml
+
+    This is the prompt as used by the grml-live system <http://grml.org>. It is
+    a rather simple one-line prompt, that by default looks something like this:
+
+        <user>@<host> <current-working-directory>[ <vcs_info-data>]%
+
+    The prompt itself integrates with zsh's prompt themes system (as you are
+    witnessing right now) and is configurable to a certain degree. In
+    particular, these aspects are customisable:
+
+        - The items used in the prompt (e.g. you can remove \`user' from
+          the list of activated items, which will cause the user name to
+          be omitted from the prompt string).
+
+        - The attributes used with the items are customisable via strings
+          used before and after the actual item.
+
+    The available items are: at, battery, change-root, date, grml-chroot,
+    history, host, jobs, newline, path, percent, rc, rc-always, sad-smiley,
+    shell-level, time, user, vcs
+
+    The actual configuration is done via zsh's \`zstyle' mechanism. The
+    context, that is used while looking up styles is:
+
+        ':prompt:grml:<left-or-right>:<subcontext>'
+
+    Here <left-or-right> is either \`left' or \`right', signifying whether the
+    style should affect the left or the right prompt. <subcontext> is either
+    \`setup' or 'items:<item>', where \`<item>' is one of the available items.
+
+    The styles:
+
+        - use-rprompt (boolean): If \`true' (the default), print a sad smiley
+          in $RPROMPT if the last command a returned non-successful error code.
+          (This in only valid if <left-or-right> is "right"; ignored otherwise)
+
+        - items (list): The list of items used in the prompt. If \`vcs' is
+          present in the list, the theme's code invokes \`vcs_info'
+          accordingly. Default (left): rc change-root user at host path vcs
+          percent; Default (right): sad-smiley
+
+    Available styles in 'items:<item>' are: pre, post. These are strings that
+    are inserted before (pre) and after (post) the item in question. Thus, the
+    following would cause the user name to be printed in red instead of the
+    default blue:
+
+        zstyle ':prompt:grml:*:items:user' pre '%F{red}'
+
+    Note, that the \`post' style may remain at its default value, because its
+    default value is '%f', which turns the foreground text attribute off (which
+    is exactly, what is still required with the new \`pre' value).

+  Usage: grml_theme_add_token <name> [-f|-i] <token/function> [<pre> <post>]
+
+    <name> is the name for the newly added token. If the \`-f' or \`-i' options
+    are used, <token/function> is the name of the function (see below for
+    details). Otherwise it is the literal token string to be used. <pre> and
+    <post> are optional.
+
+  Options:
+
+    -f <function>   Use a function named \`<function>' each time the token
+                    is to be expanded.
+
+    -i <function>   Use a function named \`<function>' to initialise the
+                    value of the token _once_ at runtime.
+
+    The functions are called with one argument: the token's new name. The
+    return value is expected in the \$REPLY parameter. The use of these
+    options is mutually exclusive.
+
+  Example:
+
+    To add a new token \`day' that expands to the current weekday in the
+    current locale in green foreground colour, use this:
+
+      grml_theme_add_token day '%D{%A}' '%F{green}' '%f'
+
+    Another example would be support for \$VIRTUAL_ENV:
+
+      function virtual_env_prompt () {
+        REPLY=\${VIRTUAL_ENV+\${VIRTUAL_ENV:t} }
+      }
+      grml_theme_add_token virtual-env -f virtual_env_prompt
+
+    After that, you will be able to use a changed \`items' style to
+    assemble your prompt.
