-# HOW TO WRITE CONDITIONALS IN THIS FILE
-# ======================================
-#
-# In many other places, one would write a conditional that expresses all the
-# cases when a source file is used or unused, and then either add or subtract
-# it from the sources list in that case
-#
-# Since base includes so many low-level things that vary widely and
-# unpredictably for the various build types, we prefer a slightly different
-# style. Instead, there are big per-platform blocks of inclusions and
-# exclusions. If a given file has an inclusion or exclusion rule that applies
-# for multiple conditions, prefer to duplicate it in both lists. This makes it
-# a bit easier to see which files apply in which cases rather than having a
-# huge sequence of random-looking conditionals.
