+# Overall strategy for what sorts of builds to include:
+# We want a build for each compiler and each platform.
+# For PRs, we lessen the "each compiler" requirement to just covering the newest
+# and oldest relevant version of each compiler.
+# We also want to ensure that each of the following tweaks are covered in at
+# least one PR build:
+# - TILES=1
+# - SOUND=1
+# - RELEASE=1
+# - CMAKE=1
+# - SANITIZE=address
+# - LOCALIZE=0
+# - A clang-tidy run
+# We try to minimize the number of builds subject to those constraints.
