For most applications, moving ~/.kde to ~/.trinity
Doesn't the startkde script try to do this?
and replacing all instances of .kde with .trinity in the ~/.trinity folder will suffice.
Is there an automated method for doing this?
There are a few "gotchas" to be aware of (listed somewhat poorly on the Etherpad), but they do not come up very frequently in practice.
Which etherpad?
