Please specify your level of familiarity with the venomous VI PERil
\(and the VI Plan for Emacs Rescue).
You can change it at any time by typing `\\[viper-set-expert-level]'

 1 -- BEGINNER: Almost all Emacs features are suppressed.
       Feels almost like straight Vi.  File name completion and
       command history in the minibuffer are thrown in as a bonus.
       To use Emacs productively, you must reach level 3 or higher.
 2 -- MASTER: C-c now has its standard Emacs meaning in Vi command state,
       so most Emacs commands can be used when Viper is in Vi state.
       Good progress---you are well on the way to level 3!
 3 -- GRAND MASTER: Like 2, but most Emacs commands are available also
       in Viper's insert state.
 4 -- GURU: Like 3, but user settings are respected for viper-no-multiple-ESC,
       viper-ex-style-motion, viper-ex-style-editing, and
       viper-re-search variables.  Adjust these settings to your taste.
 5 -- WIZARD: Like 4, but user settings are also respected for viper-always,
       viper-electric-mode, viper-want-ctl-h-help, viper-want-emacs-keys-in-vi,
       and viper-want-emacs-keys-in-insert.  Adjust these to your taste.

Please, specify your level now: "))
