Better still would be:

@comment DISTFILE:<filename>[':' <key>=<value>]*

eg:  DISTFILE:foo:SIZE=1234:MD5=...:SHA256=...

Relying on the specific position of an item in a delimited list  
almost always comes back and bites in painful spots later on down the  
way.  Minimal extra parsing required by consumers, and bits and  
pieces can be added/removed almost at will.
