環境信息：

OS: ubuntu 18.04

REPL: emacs + slime + sbcl

package system: quicklisp

project system: clproject

1. 創建mchello工程框架

安裝quicklisp，參考 https://www.quicklisp.org/beta/

安裝quickproject

CL-USER> (ql:quickload "quickproject")
To load "quickproject":
  Load 1 ASDF system:
    quickproject
; Loading "quickproject"

("quickproject")

建立工程：

CL-USER> (quickproject:make-project #p"~/quicklisp/local-projects/mchello" :depends-on '(clim clim-lisp))

(define-mchelloapp-command (com-say :name t) ((what-to-say 'string))
  (format t "~a~%" what-to-say))
