# Most of the types below come in "open" and "closed" pairs. The open ones

# specify what information we need to know about systems in general, and the

# closed ones are sub-types representing the whitelist of systems we support in

# practice.

# Code in the remainder of nixpkgs shouldn't rely on the closed ones in

# e.g. exhaustive cases. Its more a sanity check to make sure nobody defines
|
||||
# systems that overlap with existing ones and won't notice something amiss.
