do http://reboltutorial.com/source/rebol-twitter.r

You can now tweet in one line by typing:

tweet "Hello World!"

The first time it will ask your login and password:

The second and next time, you don’t need to re-enter your login and password:

You can switch to another account with the tweetaccount command like this:

tweetaccount "reboltutorial" "thisisnotmytruepassword!" "So you cannot try this for real !"
