crearting a patch

[Riccardo Mottola]

Hi all,

I need a quick "memory refresh". I rember that one could tinker in the 
source files until a package build and then issue a command to 
automatically get the patch done.
What was the command?

"gmake makepatch" fails.
"svn diff" shows nothing, since the chnge is not in the receipe, but in 
the source code!"

"mgar makepatch" does soemthing which I do not understand, but not a 
patch....
