Use it

With the cairn tool:

cairn add cairn@^0.2.1

Which writes cairn.toml, and the lakefile and SwiftPM lines that it keeps in step:

[dependencies]
cairn = "^0.2.1"

cairn.toml

[[require]]
name = "cairn"
scope = "iamnbutler"
version = "^0.2.1"

Claims in 0.2.1

Every id this package has issued, as its claims.lock held them at this version. An id never moves or changes meaning: the registry refuses a version that drops, renumbers or redefines one. The claim pages show each claim by place, with what it does and its evidence.
