argv = ARGV.map(&:downcase)

help = "\nUsage : `liste` or `liste [arguments]` or 
`liste .listname \"task\"` or `liste .listname [arguments]`

Liste is for those who have short-term memory and
those who need constant reminders.
You should add the line 'liste login' to your .bashrc

When adding an item to a list, the content MUST contain whitespace to be
selected, this is accomplished by adding quotes around your list item :
`liste .list \"my content has whitespace\"` This is done to prevent the shell
from splitting your content into seperate arguments.

--------------------------------------------------

\"task to do\"            :  add 'task' to the todo list
.login \"task to do\"     :  add 'task' to the login list
.anylist disp           :  display the contents of 'anylist'
