learning to carbonize?

[Anand Keathley]

Oh Great and Mighty OZ!

Oops!

Ok, hi everybody.  I'm thinking with the new Macs unable to boot into 
OS 9 there will be a greater desire to translate some older programs.  
Can a G5 even use Classic?  Anyway, I believe the process of adding 
something (plug-in?) to an OS 9 program so it can be used in OS X is 
called "carbonizing."  Where can one learn how to do this?  I'm 
thinking specifically about apps "Outlook Express," for OS 9, which is 
free, compared to "Entourage" for OS X which is not.  There are many 
who simply do not require the latest bells and whistles as long as they 
can retain the functions they are use to at a quicker speed.  On the 
Apple OS X download page there are many game plug-ins that allow one to 
make OS 9 games playable in OS X.  So, how does one learn to do this?

Thank you oh wise and wonderful...

Well, thanks anyway;-)
