+     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.
+
+  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.
