 ]
+
+     is the name for the newly added token. If the \`-f' or \`-i' options
+    are used,  is the name of the function (see below for
+    details). Otherwise it is the literal token string to be used. 
 and
+     are optional.
+
+  Options:
+
+    -f    Use a function named \`' each time the token
+                    is to be expanded.
+
+    -i    Use a function named \`' 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. :)
