+ 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: rc, rc-always, change-root, user, at, host, path,
+ vcs, percent, sad-smiley, battery.
+
+ 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: rc user change-root at host path vcs precent
+
+ 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).
