;; This is a minimal \`helm' configuration to discover \`helm' or debug it.\n\
;; You can retrieve this minimal configuration in \"$CONF_FILE\" \n\
;; Some originals emacs commands have been replaced by own \`helm' commands:\n\n\
;; - \`find-file'(C-x C-f) =>\`helm-find-files'\n\
;; - \`occur'(M-s o) =>\`helm-occur'\n\
;; - \`list-buffers'(C-x C-b) =>\`helm-buffers-list'\n\
;; - \`completion-at-point'(M-tab) =>\`helm-lisp-completion-at-point'[1]\n\
;; - \`dabbrev-expand'(M-/) =>\`helm-dabbrev'\n\n\
;; Some others native emacs commands are \"helmized\" by \`helm-mode'.\n\
;; [1] Coming with emacs-24.4 \`completion-at-point' is \"helmized\" by \`helm-mode'\n\
;; which provide helm completion in many other places like \`shell-mode'.\n\
;; You will find embeded help for most helm commands with \`C-c ?'.\n\
