+# NOTE(Qyriad): This file is one big slab of boilerplate.
+# Lix's current unit test organization is scattered and entagled.
+# Each of the test-support libraries could theoretically be a somewhat self-contained
+# subdir(), but literally nothing else can. Each of the tests have dependencies on other
+# test support libraries, and so do their support libraries.
+# Each of the tests have dependencies on their own andother test support libraries,
+# and so do their support libraries, and they have entangled dependencies on Lix's mainline
+# lib* targets as well.
+# The only boilerplate reduction I really could do here is throw everything in big nested dictionaries
+# and dynamically generate and refer to targets based on abstracted specs, but without user-defined
+# functions, the result would be way less readable than just a bit of copypasta.
+# It's only ~200 lines; better to just refactor the tests themselves which we'll want to do anyway.
