Subject: [PATCH] zshrc: Add a warning about the new zshrc setup files

Since a lot of people will have the .zshrc file from /etc/skel in
their home directory, this should be the-right-thing-to-do[tm].

This adds /etc/skel/zshrc.pre to stop this warning, because it is
useless on grml systems where an up-to-date set of skel files is
used.

+The configuration is kept only in one file, being the global zshrc.
+In the past, the configuration was split in two files, with the
+second file being the .zshrc file from /etc/skel.
+
+If you have a .zshrc file in your home directory that originally
+came from the skel directory, please remove it. This is also the case
+if you followed earlier instructions from the grml-zsh-refcard or
+from <http://grml.org/console> on non-grml systems.
+
+Please see the current grml-zsh-refcard for updated installation
+information. In short, you don'\''t want a .zshrc.global file. Install
+the global zshrc to ~/.zshrc and be done.
+
+If you need changes to the configuration, use ~/.zshrc.pre and
+~/.zshrc.local.

+To remove this warning execute '\''grml_do_not_warn_skel'\''.
