When to use TMPPLIST instead of pkg-plist?

[Mateusz Piotrowski]

Hello ports@,

recently I saw TMPPLIST being used for a relatively simple fonts port 
instead of pkg-plist to keep track of files to be installed by a port. I 
am quite surprised because I've always thought that this mechanism is 
reserved for special cases such as autoplist for Python packages.

Do we have any (perhaps unwritten) policy for when to use TMPPLIST? And 
when should a port maintainer stick to pkg-plist?

Cheers,

Mateusz
