[Newbies] SMMaintainableObject?

[stéphane ducasse]

To complement: in general do not through away your changes and image  
(use them always in couple the changes contains the log of what you  
did and can be handy to rescue some code). but do not forget to save  
your code either as fileout (click on class category -> fileout) or

use Monticello to save your code (my preferred way) Create an account  
on squeaksource and use Monticello
This way you will have a version on your disc
you can have a look at my videos.....http://www.iam.unibe.ch/~ducasse/
