-    # zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
-    #
-    # 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
-    # be called.
-    #
-    # 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
-    #      start *every* profile function you create like this:
-    #
-    #   function chpwd_profile_myprofilename() {
-    #       [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
-    #       print "chpwd(): Switching to profile: $profile"
-    #     ...
-    #   }
-    #
-    #      That makes sure you only get notified if a profile is *changed*,
-    #      not everytime you change directory, which would probably piss
-    #      you off fairly quickly. :-)
-    #
-    # There you go. Now have fun with that.

-Main configuration of zsh happens in /etc/zsh/zshrc.
-That file is part of the package grml-etc-core, if you want to
-use them on a non-grml-system just get the tar.gz from
-http://deb.grml.org/ or (preferably) get it from the git repository:
-
-  http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc
-
-This version of grml'\''s zsh setup does not use skel/.zshrc anymore.
-The file is still there, but it is empty for backwards compatibility.
-
-For your own changes use these two files:
-    $HOME/.zshrc.pre
-    $HOME/.zshrc.local
-
-The former is sourced very early in our zshrc, the latter is sourced
-very lately.
-
-System wide configuration without touching configuration files of grml
-can take place in /etc/zsh/zshrc.local.
-
-For information regarding zsh start at http://grml.org/zsh/
-
-Take a look at grml'\''s zsh refcard:
-% xpdf =(zcat /usr/share/doc/grml-docs/zsh/grml-zsh-refcard.pdf.gz)
-
-Check out the main zsh refcard:
-% '$BROWSER' http://www.bash2zsh.com/zsh_refcard/refcard.pdf
-
-And of course visit the zsh-lovers:
-% man zsh-lovers
-
-You can adjust some options through environment variables when
-invoking zsh without having to edit configuration files.
-Basically meant for bash users who are not used to the power of
-the zsh yet. :)

-  "NOMENU=1   zsh" => do not use auto menu completion

-  "NOPRECMD=1 zsh" => disable the precmd + preexec commands (set GNU screen title)
-  "NOTITLE=1  zsh" => disable setting the title of xterms without disabling
-                      preexec() and precmd() completely
-  "BATTERY=1  zsh" => activate battery status (via acpi) on right side of prompt

+# Guidelines for adding key bindings:

+#   - Do not add hardcoded escape sequences, to enable non standard key
+#     combinations such as Ctrl-Meta-Left-Cursor. They are not easily portable.
+#
+#   - Adding Ctrl characters, such as '^b' is okay; note that '^b' and '^B' are
+#     the same key.
+#
+#   - All keys from the $key[] mapping are obviously okay.
+#
+#   - Most terminals send "ESC x" when Meta-x is pressed. Thus, sequences like
+#     '\ex' are allowed in here as well.

+function prompt_grml_help () {
+    <<__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
+
+        - strip-sensitive-characters (boolean): If the \`prompt_subst' option
+          is active in zsh, the shell performs lots of expansions on prompt
+          variable strings, including command substitution. So if you don't
+          control where some of your prompt strings is coming from, this is
+          an exploitable weakness. Grml's zsh setup does not set this option
+          and it is off in the shell in zsh-mode by default. If it *is* turned
+          on however, this style becomes active, and there are two flavours of
+          it: On per default is a global variant in the '*:setup' context. This
+          strips characters after the whole prompt string was constructed. There
+          is a second variant in the '*:items:<item>', that is off by default.
+          It allows fine grained control over which items' data is stripped.
+          The characters that are stripped are: \$ and \`.
+
+    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).

+    -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.
+
+    There is a utility function \`grml_theme_has_token', which you can use
+    to test if a token exists before trying to add it. This can be a guard
+    for situations in which a \`grml_theme_add_token' call may happen more
+    than once.
+
+  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.

+Main configuration of zsh happens in /etc/zsh/zshrc.
+That file is part of the package grml-etc-core, if you want to
+use them on a non-grml-system just get the tar.gz from
+http://deb.grml.org/ or (preferably) get it from the git repository:
+
+  http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc
+
+This version of grml'\''s zsh setup does not use skel/.zshrc anymore.
+The file is still there, but it is empty for backwards compatibility.
+
+For your own changes use these two files:
+    $HOME/.zshrc.pre
+    $HOME/.zshrc.local
+
+The former is sourced very early in our zshrc, the latter is sourced
+very lately.
+
+System wide configuration without touching configuration files of grml
+can take place in /etc/zsh/zshrc.local.
+
+For information regarding zsh start at http://grml.org/zsh/
+
+Take a look at grml'\''s zsh refcard:
+% xpdf =(zcat /usr/share/doc/grml-docs/zsh/grml-zsh-refcard.pdf.gz)
+
+Check out the main zsh refcard:
+% '$BROWSER' http://www.bash2zsh.com/zsh_refcard/refcard.pdf
+
+And of course visit the zsh-lovers:
+% man zsh-lovers
+
+You can adjust some options through environment variables when
+invoking zsh without having to edit configuration files.
+Basically meant for bash users who are not used to the power of
+the zsh yet. :)
+
+  "NOCOR=1    zsh" => deactivate automatic correction
+  "NOMENU=1   zsh" => do not use auto menu completion
+                      (note: use ctrl-d for completion instead!)
+  "NOPRECMD=1 zsh" => disable the precmd + preexec commands (set GNU screen title)
+  "NOTITLE=1  zsh" => disable setting the title of xterms without disabling
+                      preexec() and precmd() completely
+  "GRML_DISPLAY_BATTERY=1  zsh"
+                   => activate battery status on right side of prompt (WIP)
+  "COMMAND_NOT_FOUND=1 zsh"
+                   => Enable a handler if an external command was not found
+                      The command called in the handler can be altered by setting

+                      "/usr/share/command-not-found/command-not-found"
+
+A value greater than 0 is enables a feature; a value equal to zero
+disables it. If you like one or the other of these settings, you can
